Question

find the value of x
4x-8=40​

Answer 1

Answer:

$= > 4x - 8 = 40 \\ = > 4x = 40 + 8 \\ = > 4x = 48 \\ = > x = \frac{48}{4} \\ = > x = 12$

Answer 2

Simplifying :

4x + -8 = 40

Reorder the terms :

-8 + 4x = 40

Solving :

-8 + 4x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 4x = 40 + 8

Combine like terms:

-8 + 8 = 0

0 + 4x = 40 + 8

4x = 40 + 8

Combine like terms:

40 + 8 = 48

4x = 48

Divide each side by '4'.

x = 12

Simplifying

x = 12
