Question

X + x+2+x+4+x+6= -28 state the property that justifies your first step and why you chose it.

Answer 1

x + x + 2 + x + 4 + x + 6 = -28

There are four x's, so 4x.

And 2 + 4 + 6 is 12.

4x + 12 = -28

Isolate the variable term.

4x = -40

Isolate the variable.

x = -10

Answer 2

4x+12=-28

x+3=-7

x=-11
