Question

1) What can u do to get 2x alone on the left side?

Answer 1

Answer:

1)

82.5 - 82.5 + 2x = 338.5 - 82.5

2x = 256

2)

2x ÷ 2 = 256 ÷ 2

x = 128

Step-by-step explanation:

1)

In order to get rid 82.5, you have to substract the same value on both side to get a 0 value.

2)

In order to find the value of x, you have to divide the value that is sticked with x which is 2. As you divide 2 by 2, you will get 1 as a single value of x so you have to divide 2 to both side too.
