You have to multiply whatever number your working with by 2
Convert the first to an equation:
6(x+15)=-42
6x+90=-42
6x=132
x=22
Same for second equation:
4(x-7)=12
4x-28=12
4x=40
x=10
The solutions are x=22 and x=10
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
