Answer 2

To solve the equation, let's simplify it step by step:

-2×(3.1x-1) + 3×(1.2x+1) = -4.5

First, distribute the multiplication:

-6.2x + 2 + 3.2x + 3 = -4.5

Combine like terms:

(-6.2x + 3.2x) + (2 + 3) = -4.5

-3x + 5 = -4.5

Next, isolate the variable term:

-3x = -4.5 - 5

-3x = -9.5

Now, divide both sides of the equation by -3 to solve for x:

x = (-9.5) / (-3)

x ≈ 3.1667

Therefore, the solution to the equation -2×(3.1x-1) + 3×(1.2x+1) = -4.5 is approximately x = 3.1667.
