Question

Solve the equation and check the solution:7x - 7 = 13 + 12x

Answer 1

we have the equation

7x - 7 = 13 + 12x​

solve for x

Group terms

12x-7x=-7-13

Combine like terms

5x=-20

x=-20/5

x=-4

Verify

substitute the value of x=-4 in the original expression

7(-4)-7=13+12(-4)

-28-7=13-48

-35=-35 -------> is ok
