Answer 1

Hello!

Let’s work this out step by step.

The first thing you want to do is move that 48 to the other side. To do that, add 48 to both sides:

7x-5x/3(20x-8)=48

Now, the equation isn’t equal to zero… so it is solvable! Remember in order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction. So, let’s start by multiplying the (-5x/3) by the components inside the parentheses to get rid of the parentheses altogether!

7x-100x/3x+40x/3=48

Since both the numerator and denominator have an “x” in them in “100x/3x”, you can cancel out the “x”s to just get 100/3, which is 33.333333

7x-100/3+40x/3=48

Let’s get rid of that 100/3 by adding it to both sides.

7x+40x/3=81.33333333333

Transform 7x to a fraction that can be added to 40x/3 (common denominators)

7x=7x/1

7x/1* (3/3)= 21x/3

Now, add the two fractions together

21x/3+40x/3= 61x/3

61x/3=81.333333333

Get rid of the 3 by multiplying on both sides:


61x= 244

Divide by 61 to get x

X=4
