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.
