Answer:

x = - 1

Step-by-step explanation:

7 (4x + 1) – 3x = 5x – 13

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

25x + 7 = 5x - 13

25x - 5x = -13 - 7

20x = -20

x = -20/20

x = -1

Answer: x = -1

Step-by-step explanation:

[tex]7 (4x + 1) -3x = 5x-13[/tex]

Distribute 7.

[tex]28x+7-3x=5x-13[/tex]

Subtract 7.

[tex]28x-3x=5x-13-7[/tex]

Subtract 5x

[tex]28x-3x-5x=-13-7[/tex]

Combine like terms;

[tex]20x=-20[/tex]

Divide by 20.

[tex]x=\frac{-20}{20}\\ x=-1[/tex]
