Question

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

Answer 1

x = 12

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

Answer 2

12

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
