Question

Given:3(x-4)=33 Prove: x=15

Need help on proofing these with the reasons in 10 steps

Answer 1

Do you have to have it in at least 10 steps? I can show you in about 7 if thats ok?

Answer 2

3(x-4)=33 Expand the bracket
3(x)-4(3)=33
3x-12=33 Add both sides by 12
3x=33+12
3x=45 Divide both sides by 3 to get x on its own
x=45/3
x=15

Answer 3

you can do it in two steps
1) divide by 3
2) add 4
