Find the roots
y=1
Evaluate
(4y−8)−(−3y−1)
To find the roots of the expression,set the expression equal to 0
(4y−8)−(−3y−1)=0
Remove the parentheses
4y−8−(−3y−1)=0
Subtract the terms

Add the numbers
7y−7
7y−7=0
Move the constant to the right-hand side and change its sign
7y=0+7
Removing 0 doesn't change the value,so remove it from the expression
7y=7
Divide both sides
77y=77
Divide the numbers
y=77
