FILL IN THE BLANK QUESTION

1 min • 1 pt

Simplify the equation. Solve for x


2x + 3x - 5 + 7 = 10x + 3 - 6x - 4

Answer explanation

First we simplify both sides of the equation.

2x + 3x - 5 + 7 = 10x + 3 - 6x - 4 Original problem


2x + 3x - 5 + 7 = 10x + 3 - 6x - 4

5x + 2 = 4x - 1 Combine like terms on each side of the equation


Next we want all terms with a variable one one side of the equation and all numbers on the other side.


5x - 4x + 2 = 4x - 1 - 4x Subtract 4x from both sides

x + 2 - 2 = - 1 - 2 Subtract 2 from both sides to get x alone

x = - 3 Combine like terms

FILL IN THE BLANK QUESTION

Simplify the equation. Solve for x.

6(2x - 1) - (11x +6) = 7

Answer explanation

Use the distributive property

6(2x) + 6(- 1) - 1(11x) - 1(6) = 7 Apply the distributive property (multiply)

12x - 6 - 11x - 6 = 7

x - 12 = 7 Combine like terms

x - 12 + 12 = 7 + 12 Add 12 to both sides

x = 19 Simplify
