Answer:

Step-by-step explanation:

Set up and solve an equation of ratios. One such equation would be:

5 40

--- = ------------

3 2x + 10

Cross multiplying, we get:

10x + 50 = 120, or 10x = 70. thus, x = 70/10, or x = 7.

4x+3=-5 helppp please

Goryan [66]

Answer: x = -2

Step-by-step explanation: To solve for x, in the equation you see here, our goal is to get x by itself.

Our first step will be to isolate the term containing x which in this case is 4x. To isolate 4x, we have to get rid of the +3 by subtracting 3 from both sides of the equation. On the left, +3 and -3 cancel out and we're left with 4x. On the right, -5 - 3 simplifies to -8.

Now we have the equation 4x = -8.

To get x by itself, we divide both sides of the equation by 4. On the left, the 4's cancel and on the right, -8 divided by 3 is -2 so x = -2
