Question

5(3​x​ + 7) = 20 – 2(​x​ + 1)

Answer 1

50x

Explanation:

Lets start!

5(3​x​ + 7) = 20 – 2(​x​ + 1)

So as we should know we have 'PEMDAS' standing for parenthesis, exponents, multiplication, division, and subtraction. You do math (any math) in the order of PEMDAS.

So lets start out with the parenthesis:

(3x +7) is 10x and (x +1) is 1x

now lets multiply:

So now we have that the equation is

5 · 10x · 1x

5 · 10x is 50x and 50 · 1x is 50x

Therefore our answer is 50x.

Hope this helped have a fantastic day! (✿◡‿◡)
