"can you check if i have this one right 0.6x+2=1.4x-1

my answer is ≥ 3.75 im i correct"

You have correctly solved the equation to get x=3/0.8 = 3.75.

However your statement of x≥3.75 would be incorrect since the question given is an equation, and not an inequality.

To solve the equation using the multiplication principle, follow these steps:

Step 1: First, eliminate the fraction by multiplying both sides of the equation by the reciprocal of the coefficient of x. The reciprocal of -1/2 is -2/1 (or simply -2).

(-2/1) * (-1/2x) = (-2/1) * (-3/4)

Simplifying this gives:

x = 6/4

Step 2: Next, simplify the fraction on the right side of the equation by reducing it to its simplest form.

x = 3/2

So, the solution to the equation -1/2x = -3/4 is x = 3/2.
