40=-0.2x+45
i cant seem to solve this problem.
40=-0.2x+45
Subtract 45 to both sides
-5=-0.2x
now divide -0.2 to both sides
-5/-0.2=x
A negative divdes by a negative gives you a positive
5/0.2=x
You can leave that like that or find the decimal form of it.
40=-0.2x+45
0.2x = 45 - 40
0.2x = 5
x = 5/0.2
x = 25
Checking:
40 = -0.2x + 45
40 = -0.2 (25) + 45
40 = -5 + 45
Thank you sooo much!
To solve this equation, you need to isolate the variable x on one side of the equation. Here's how you can do it step by step:
Step 1: Start by subtracting 45 from both sides of the equation to get rid of the constant term on the right side:
40 - 45 = -0.2x + 45 - 45
-5 = -0.2x
Step 2: Now, we want to isolate x. Divide both sides of the equation by -0.2 to solve for x:
-5 / -0.2 = (-0.2x) / -0.2
25 = x
So, the solution to the equation is x = 25.
