Question

8.8 + 7.8x = -7.9 - 5.5x

Answer 1

`-(16.7)/(13.3)`

Explanation:

Step 1: Collect the like terms

8.8 + 7.9 = -5.5x - 7.8x

Step 2: Simplify

16.7 = -13.3x

Step 3: Divide both sides by -13.3

`(16.7)/(-13.3) =(-13.3)/(-13.3)x`

`x =- (16.7)/(13.3)`

Therefore the answer is
`-(16.7)/(13.3)`

Answer 2

x = -1 34/133

Explanation:

Given

8.8 +7.8x = -7.9 -5.5x

13.3x = -16.7 . . . . . . . . . . . add 5.5x -8.8

x = -16.7/13.3 = -167/133 . . . . divide by 13.3 and simplify

x = -1 34/133 ≈ -1.25564
