Question

What is the value of y? 6(5 + 3) = 6 • 5 + 6 • y

Answer 1

$6(5+3)=6\cdot5+6\cdot y\\\\6(8)=30+6y\\\\48=30+6y\ \ \ \ |subtract\ 30\ from\ both\ sides\\\\18=6y\ \ \ \ |divide\ both\ sides\ by\ 6\\\\3=y\\\\\huge\boxed{y=3}$

Answer 2

6(5+3)=(6)(5)+6y

Simplify

6(5+3)=(6)(5)+6y

48=30+6y

48=6y+30

Flip the equation.

6y+30=48

Subtract 30 from both sides.

6y+30−30=48−30

6y=18

Divide both sides by 6.

6y / 6 = 18/ 6

y=3
