Answer:
1) (2,10) is solution of y=4x+2
2) (7,5) is not solution of 2x+y=5
3) (-3,3) is not solution of y=6-x
4) (10,-1) is solution of x+8y=2
5) (2,21) is not solution of y=6x+7
6) (6,-8) is solution of 3x-y=26
Step-by-step explanation:
1) y=4x+2 (2,10)
Put x=2 and y=10 and check if both sides are equal or not
10=4(2)+2
10=8+2
10=10
So, (2,10) is solution of y=4x+2
2) 2x+y=5 (7,5)
Put x=7 and y=5 and check if both sides are equal or not
2x+y=5
2(7)+5=5
14+5=5
19≠5
So, (7,5) is not solution of 2x+y=5
3) y=6-x (-3,3)
Put x=-3 and y=3 and check if both sides are equal or not
y=6-x
3=6-(-3)
3=6+3
3≠9
So, (-3,3) is not solution of y=6-x
4) x+8y=2 (10,-1)
Put x=10 and y=-1 and check if both sides are equal or not
x+8y=2
10+8(-1)=2
10-8=2
2=2
So, (10,-1) is solution of x+8y=2
5) y=6x+7 (2,21)
Put x=2 and y=21 and check if both sides are equal or not
y=6x+7
21=6(2)+7
21=12+7
21≠19
So, (2,21) is not solution of y=6x+7
6) 3x-y=26 (6,-8)
Put x=6 and y=-8 and check if both sides are equal or not
3x-y=26
3(6)-(-8)=26
18+8=26
26=26
(6,-8) is solution of 3x-y=26

x2-11x+18=0 need help!
Answers
Answer:
x = 2 or
x = 9
Step-by-step explanation:
x² - 11x + 18 = 0
x² - 9x - 2x + 18 = 0
x(x - 9) - 2(x - 9) = 0
(x - 2)(x - 9) = 0
x - 2 = 0 or x - 9 = 0
x = 2 or x = 9
Thus, x = 2 or 9
-TheUnknownScientist
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 2 and - 9 , since
- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus
(x - 2)(x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 9 = 0 ⇒ x = 9
solve for x -2(-x+1)+3x+3=26

What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS

we have,
Step 1: Define
f(x) = 2x - 5
f(x) = 15
Step 2: Solve for x
Substitute in f(x) [Function]: 15 = 2x - 5
[Addition Property of Equality] Add 5 on both sides: 20 = 2x
[Division Property of Equality] Divide 2 on both sides: 10 = x
Rewrite: x = 10
hence, The solution is : the value of x that makes f(x) = 15, is x = 10.
