Question 300567
what does x equal in 7x+2=12+5x. and how do you figure that out 

7x + 2 = 12 + 5x

Substract 5x from both sides of the equation:

7x - 5x + 2 = 12 + 5x - 5x

2x + 2 = 12 

Now subtract 2 from both sides:

2x + 2 - 2 = 12 - 2

2x = 10

Divide both sides of the equation above by 2:

2x/2 = 10/2

x = 5
