Question

Solve for x.

−4.84 = −1.3x + 2.7

A) −4.6
B) −2.9
C) 4.7
D) 5.8

Answer 1

The answer is D: 5.8.

Explanation:

1. Let's move all of our known numbers to the left side
2. This way we get this: -4.84 - 2.7=1.3x
3. If we subtract those numbers: -5.8=-1.3x
4. You can times the whole equation by '-1'. You will get 5.8=1.3x
5. To find x, divide the whole equation by '1.3', you will get x=5.8/1.3
6. When we divide 5.8 by 1.3, we get 5.8. That means x=5.8
