Given: 3y+2=11 Prove: y=3

Question

Statements:

Reasons:

Answer 1

subtract 2 from both sides

or add -2 to both sides

equals added to equals are equal

3y+2-2 = 11-2

3y = 9

divide by 3

y = 9/3 = 3

or you could have just replaced y by 3 in the original equation

3(3)+ 2 = 11

9+2 = 11

11 = 11
