x+6=24

Question

x+6+(-6)=24 +(-6)
x= 18 is this right.

3(x+4)=5(x-2)
3x+12=5x-10
3x-5x=12-10
2x=-22
x=-11 is this problem right

Answer 1

This first one is right. The second one, I think you did your math wrong

3x-5x=-10-12
-2x=-22
x=11

Answer 2

3x-5x gives you -2x not 2x and on 12-10 does not give you 22

your suppose to subtract 12 from both sides
