3(2x - 3) + x = 4(x + 2)

Vinil7 [7]

Answer:

x = 17/3

Step-by-step explanation:

3(2x - 3) + x = 4(x + 2)

7x - 9 = 4x + 8

Add 9 to both sides:

7x - 9 + 9 = 4x + 8 + 9

Simplify:

7x = 4x + 17

Subtract 4x from both sides:

7x - 4x = 4x + 17 - 4x

Simplify:

3x = 17

Divide both sides by 3:

3x/3 = 17/3

x = 17/3

Hope this helps!!
