Answer: 4x+2(x+12)=27
Step-by-step explanation: The first equation, y=x+12 shows what y is, so you can just add it into the equation with parentheses. If the y is next to a number, it means that whatever y is (in this case, it’s x+12), y will multiply by the number next to it, (2, in this case). Then you can just solve from there for x.
