Final answer:
To solve the equation -1.2x+2.5=0.8x+6.5, rearrange the equation to isolate x on one side. Divide both sides by 0.4 to solve for x. The value of x is 10.
Step-by-step explanation:
To solve the equation -1.2x+2.5=0.8x+6.5, we need to move all the terms involving x to one side of the equation. Adding 1.2x to both sides and subtracting 2.5 from both sides, we get 2.5-1.2x=6.5-0.8x. Simplifying, we have 0.4x=4. Now divide both sides by 0.4 to find the value of x. Therefore, x=10.
