Question

Solve to find the value for x in the linear equation: 36-4x + 5) = 12

CIE
1 Use the distributive property:
2 Use the subtraction property of equality
3. Division property of equality:
3(-4x) + 3(5) = 12
-12x + 15 = 12
- 12x + 15 - 15 = 12 - 15
-12x = -3
Intro

Answer 1

`(1)/(4)`

Explanation:

Given expression:

3(-4x + 5) = 12

To solve for x;

Use the distributive property to open the parentheses;

3(-4x) + 3(5) = 12

-12x + 15 = 12

then, add -15 to both sides;

-12x + 15 + (-15) = 12 + (-15)

-12x = -3

divide both sides by -12;

`(-12x)/(-12)` =
`(-3)/(-12)`

x =
`(1)/(4)`
