-3 + 7*(2.5x - 7.6) = -3.66 + 2.1x
Expand the left side:
-3 + 17.5x - 53.2 = -3.66 + 2.1x
Combine like terms:
17.5x - 56.2 = -3.66 + 2.1x
Now, isolate the variable x:
Subtract 2.1x from both sides:
17.5x - 2.1x - 56.2 = -3.66
15.4x - 56.2 = -3.66
Add 56.2 to both sides:
15.4x = 52.54
Divide by 15.4 to solve for x:
x = 3.41
Therefore, the solution to the equation is x = 3.41.
