Step-by-step explanation:
To solve this, we must follow the PEMDAS rule:
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
So lets start on the left equation:
Since parenthesis is first, we must do this:
(150 - 168 + 24)
168 + 24
==> 192
192 - 150
==> 42
So right now we have:
(
+ 42 -

Do the exponents now:
and
= 25
64 + 42 - 25
64 + 42
==> 106
106 - 25
==> 81
So now we have 81 for the left equation, now for the right:
(3 × 5 - 3 × 2²)
Exponents first:
![2^(2) = 4](https://img.qammunity.org/2020/formulas/advanced-placement-ap/middle-school/gcs3vvoyyjb31nfe4via2cdjetht3jucur.png)
(3 × 5 - 3 × 4)
3 * 5
==> 15
3 * 4
==> 12
15 - 12
==> 3
So now we should be with:
81 divided by 3
81 ÷ 3
==> 27
