Question

3(4y-1)=2(5y+1/2) solve for y.

Answer 1

use distributive property
a(b+c)=ab+ac
distribute
3(4y-1)=12y-3
2(5y+1/2)=10y+1
so nowe we have

12y-3=10y+1
subtract 10y from both sides
2y-3=1
add 3
2y=4
divide 2
y=2

y=2

Answer 2

3(4y-1)=2(5y+1/2) distribute

12y-3=10y+1   

12y=10y +4

2y=4 divide each side by 2

4 divided by 2 equals 2

The answer is y=2
