Question

Solve for y:
x-0.25y=1.5

Answer 1

To find value of y in times o x we have to transfrom this equation.
LEts do this
x-0.25y=1.5           /-x subtract x both sides
-0.25y=1.5-x                /*4 multiply by 4 both sides
-0.25y*4=4(1.5-x)          
-1y=6-4x          /*-1     multiply both sides by -1
y=4x-6

Answer 2

x-0.25y = 1.5    Rearrange the equation with y on the left hand side.
                        Since we are solving for y.
-0.25y = 1.5 -x  
-0.25y = -x + 1.5       Divide both sides by -0.25.

y = (-x + 1.5)/-0.25 

y = -4*(-x +1.5) = 4x -6.

y = 4x - 6.
