Ineed with six times the sum of a number and 15 is -42 and four times the difference of a number and 7 is 12 i'm really bad at problems like these

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!
