Answer 1

Step-by-step explanation:

8x-3x=40

5x=40

x=40/5

x=8

Answer 2

Answer:

$\Large\boxed{X=8}$

Step-by-step explanation:

QUESTION:

8x - 3x = 40

GIVEN:

To solve this problem, first you isolate it by the x from one side of the equation from left to right. You can also solve with distributive property.

$\Large\boxed{\textnormal{DISTRIBUTIVE PROPERTY}}}$

$\displaystyle A(B+C)=AB+AC$

SOLUTIONS:

First, add or subtract the numbers from left to right.

$\displaystyle 8x-3x=5x$

Rewrite the problem down.

$\displaystyle 5x=40$

Then, you divide by 5 from both sides of an equation.

$\displaystyle \frac{5x}{5}=\frac{40}{5}$

Solve. (Simplify.)

Divide the numbers from left to right.

$\displaystyle 40\div5=\boxed{8}$

$\Large\boxed{X=8}$

Hence, the correct answer is x=8.
