Question

1 + 7x = 5x + 25 solve for X

Answer 1

Answer:

12

Step-by-step explanation:

Start by subtracting both sides by 5x:

$1+7x-5x=25\\1+2x=25$

Subtract 1 from both sides

$2x=24$

Divide both sides by 2

$x=12$

Check

$1+7(12)=5(12)+25\\1+84=60+25\\85=85$

Therefore x = 12

Answer 2

Answer:

x = 12

Step-by-step explanation:

1 + 7x = 5x + 25 ( subtract 5x from both sides )

1 + 2x = 25 ( subtract 1 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12
