Question

4(m + 1) = 20
m=

Answer 1

divide both sides by 4 to eliminate the 4 in front of the parentheses

from there, you'll have m + 1 on the left side, so you can simply subtract 1 from both sides to get m

Answer 2

\(4(m + 1) = 20\)
The first thing you do is distribute
you will be distributing `4` to everything inside of the parenthesis
which is `m` and `1`
So
\(4*m\\4*1\)
Which gives us 4m and 4
Basically what we just did was \((4)(m)+(4)(1)=20 \longrightarrow4m+4=20\)
Then you get `+4`
change the plus `(+)` to a minus `(-)`
So now you have `-4`
now that you have `-4` you subtract 4 from both sides
which should give you \(4m=16\)
because \(4m+4−4=20−4\)
and 20-4=16
Therefore, you have \(4m=16\) \)
so the last step would be to divide 4 to both sides of the equation
\(\LARGE\frac{4m}{4}=\frac{16}{4}\)
\(\cancel{\frac{4m}{4}}=\frac{16}{4}\) (4m/4 cancels)
So all you have left is 16/4
simplify that then you should have your answer
16/4=?
m=?
