Question

8.8 + 7.8x = -7.9 - 5.5x
Round to the nearest tenth

Answer 1

The value of x in this equation is -1.3

Explanation:

8.8 + 7.8x = -7.9 - 5.5x

Subtract 8.8 on both sides of the equation.

7.8x = -16.7 - 5.5x

Add 5.5x on both sides of the equation.

13.3x = -16.7

Divide 13.3 on both sides of the equation. Don't forget to round to the nearest tenth.

x = -1.3

Answer 2

x = -1.3

Explanation:

8.8 + 7.8x = -7.9 - 5.5x

Add 5.5x to each side

8.8 + 7.8x+5.5x = -7.9 - 5.5x+ 5.5x

8.8+13.3x = -7.9

Subtract 8.8 from each side

8.8 + 13.3x - 8.8 = -7.9 - 8.8

13.3x = -16.7

Divide by 13.3

x = -16.7/13.3

x =-1.255639098

Rounding to the nearest tenth

x = -1.3
