Answer 1

Respuesta:

implifying

4x + 5 = 3x + 8

Reorder the terms:

5 + 4x = 3x + 8

Reorder the terms:

5 + 4x = 8 + 3x

Solving

5 + 4x = 8 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

5 + 4x + -3x = 8 + 3x + -3x

Combine like terms: 4x + -3x = 1x

5 + 1x = 8 + 3x + -3x

Combine like terms: 3x + -3x = 0

5 + 1x = 8 + 0

5 + 1x = 8

Add '-5' to each side of the equation.

5 + -5 + 1x = 8 + -5

Combine like terms: 5 + -5 = 0

0 + 1x = 8 + -5

1x = 8 + -5

Combine like terms: 8 + -5 = 3

1x = 3

Divide each side by '1'.

x = 3

Simplifying

x = 3
