Alternative Form
y=0.3
Evaluate
-\left(3y+7-7.9\right)
To find the roots of the expression,set the expression equal to 0
-\left(3y+7-7.9\right)=0
Subtract the numbers
-\left(3y-0.9\right)=0
Calculate
-3y+0.9=0
Move the constant to the right-hand side and change its sign
-3y=0-0.9
Removing 0 doesn't change the value,so remove it from the expression
-3y=-0.9
Change the signs on both sides of the equation
3y=0.9
Divide both sides
\frac{3y}{3}=\frac{0.9}{3}
Divide the numbers
y=\frac{0.9}{3}
Solution
