What is the vaule of m in this equation 188 = m + 80
Crazy boy [7]

Explanation:

First, switch sides of an equation.

m+80=188

Then, you subtract by the 80 from both sides of an equation.

m+80-80=188-80

And finally, simplify and subtract the numbers.

188-80=108

\boxed{m=108}

Hope this helps!

Thank you!

Have a great day!

Help? Multi-Step Equations - Fractions. Solve the Equation.<br>PLEASE DO IT STEP BY STEP (visual)
GREYUIT [131]
R - 10/3 + 1/2 = -11/6...if u multiply everything by the common denominator 6, it will get rid of the fractions.

(6)r - 6(10/3) + 6(1/2) = 6(-11/6)
6r - 60/3 + 6/2 = - 66/6...simplify
6r - 20 + 3 = - 11
6r - 17 = -11
6r = -11 + 17
6r = 6
r = 6/6
r = 1 <===
