Solve the y-variable: 5y + 1.8 = 4y - 3.2
First: combine "like" terms on one side (left)---combine the coefficients with the y-variable > subtract "4y" from both sides (when you move a term to the opposite side, always use the opposite sign)....
5y - 4y + 1.8 = 4y - 4y - 3.2
5y - 4y + 1.8 = - 3.2
y + 1.8 = - 3.2
Sec: subtract "1.8" from both sides to isolate "y" on one side...
y + 1.8 - 1.8 = - 3.2 - 1.8
y = - 3.2 - 1.8
y = - 5

are u serious?
subtract 4y both sides give you y + 1.8 = -3.2
subtract 1.8 from both sides gives you
y = -5

5y+1.8=4y-3.2
5y-4y=-3.2-1.8
y=-5

make y equal to -5 and both sides of the equation are -23.2.
