Solve for y in the equation 4y+15=-5y+9
a)-6
b) -2/3
c)2/3

Answer 1

4y + 15 = -5y + 9
4y + 5y = 9 -15
9y = -6
y = -6/9
y = -2/3

Answer 2

to solve for "Y" move them all onto one side, and all your non "Y"'s on the other

4y+5y=9-15

now simplify

9y=-6

solve for "Y"

y=-6/9

reduce

-2/3 is your answer (:
