Question

When = 3, what will the value for y be for the equation - 4x + 5y = 18?

Answer 1

Answer: y=6

-4(3)+5y=18

-12+5y=18

add 12 to both sides

-12+5y+12=18+12

5y=18+12

5y=30

divide both sides by 5

5y÷5=30÷5

y=30÷5

y=6

I hope this is good enough:

Answer 2

If x equals 3 then y must equal 1.2
