Question

solve (7 x + 3) = (2x + 13)​

Answer 1

Simplifying

7x + -3 = 2x + 13

Reorder the terms:

-3 + 7x = 2x + 13

Reorder the terms:

-3 + 7x = 13 + 2x

Solving

-3 + 7x = 13 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

-3 + 7x + -2x = 13 + 2x + -2x

Combine like terms: 7x + -2x = 5x

-3 + 5x = 13 + 2x + -2x

Combine like terms: 2x + -2x = 0

-3 + 5x = 13 + 0

-3 + 5x = 13

Add '3' to each side of the equation.

-3 + 3 + 5x = 13 + 3

Combine like terms: -3 + 3 = 0

0 + 5x = 13 + 3

5x = 13 + 3

Combine like terms: 13 + 3 = 16

5x = 16

Divide each side by '5'.

x = 3.2

Simplifying

x = 3.2
