What is the value of x in the equation 7(4x+1)−3x=5x−13?

Citrus2011 [14]

Answer:

x = -1

Step-by-step explanation:

7(4x+1)−3x=5x−13

Distribute

28x +7 -3x = 5x -13

Combine like terms

25x+7 = 5x-13

Subtract 5x from each side

25x-5x +7 = -13

20x +7 = -13

Subtract 7 from each side

20x+7-7 = -13-7

20x = -20

Divide by 20

20x/20 = -20/20

x = -1
