120=4x+1.5(60)-82
how to find x

Answer: X = 28

Step-by-step explanation:

So, in this equation, lets start with the parenthesis 1.5 multiplied by 60.

step 1: 1.5 * 60 = 90.

120 = 4x + 90 - 82.

Step 2: Lets subtract 82 from 90 because they both have no variables.

120 = 4x + 8

step 3: We need to get 4x by itself, so lets subtract 8 from both the sides.

120 - 8 = 4x + 8 - 8.

112 = 4x.

step 4: So, now 4 and x are multiplying, to reverse that operation we need to divide 4 from both the sides to get x by itself.

112/4 = 4x/4.

28 = x.

So, the value of x is 28.

To check:

We can substitute our x value to the equation.

120 = 4(28) + 1.5(60) - 82

120 = 112 + 90 - 82

120 = 112 + 8

120 = 120. Our final answer is the same. So, it is also proved.
