Solve the equation
More Steps

Evaluate
4−7y=0
Move the constant to the right-hand side and change its sign
−7y=0−4
Removing 0 doesn't change the value,so remove it from the expression
−7y=−4
Change the signs on both sides of the equation
7y=4
Divide both sides
77y=74
Divide the numbers
y=74
y=0y=74
Solution
y1=0,y2=74
Alternative Form
