Hello
All you have to do first is multiply the 3 into the x-5.
So we have 3x-15 + 7 = 16
Then add like terms: 3x-8=16.
Now add 8 to both sides: 3x=24
Now divide by 3 (same as multiplying by 1/3): x=8.
Hope this helps

3x - 15 + 7 = 16
3x - 8 = 16
3x = 24
x = 8

3(x-5)+7=16
3(x-5)= 16-7
3(x-5)= 9
(x-5) = 9/3
x-5 =3
x= 3+5
x=8

3(x-5)+7=16
3x-15+7=16
3x-24=0
x-8=0
x=8

3(x-5)+7=16
or,3x-15+7=16
or,3x=16+15-7=24
or,x=24/3=8
