Question

For which equation(s) is −2 a solution?

Answer 1

A.) 2x+6=2

B.) 2(x-4)=6x

Explanation:

A.) 2x+6=2:

Move all terms that don't contain x to the right side and solve.

x=−2

B.) 2(x-4)=6x:

Solve for x by simplifying both sides of the equation, then isolating the variable.

x=−2

C.) 3x+1/2=1/4x+6:

Solve for x by cross multiplying.

x=2

D.) 3x+15=2x+9:

Solve for x by simplifying both sides of the equation, then isolating the variable.

x=−6
