4(v + 8) = 40 Which solutions makes this equation true?

1. 2

2. 4

1. 2 as 4 x 2 is 8 and 4 x 8 is 32 so 32 + 8 = 40

2

Let’s try v = 4

4(4 + 8) = 40

PEMDAS says do what’s in the parentheses first so

4 x 12 = 40

Now multiply

4 x 12 = 48 not 40 so it’s not that

Now let’s try v = 2

4(2 + 8) = 40

Do what’s in the parentheses

4 x 10 = 40

So 2 is the answer

PEMDAS is

Parentheses
Exponents
Multiply
Divide
Add
Subtract

Hope this helps
