6.8x − (−3x+7.5 ) + 9=2x−2.4

Answer 1

To solve for x, we can simplify the left side of the equation first:

6.8x - (-3x+7.5) + 9 = 2x - 2.4

Distribute the negative sign:

6.8x + 3x - 7.5 + 9 = 2x - 2.4

Combine like terms on both sides:

9.8x + 1.5 = 2x - 2.4

Subtract 2x from both sides:

7.8x + 1.5 = -2.4

Subtract 1.5 from both sides:

7.8x = -3.9

Divide both sides by 7.8:

x = -0.5

Therefore, the solution for x is -0.5.
