I need help to solve this math problem.

-7.4=-3.7+x=

The problem is not clear, with two equal signs.

If the last equal sign is to be ignored, you have
-7.4 = -3.7 + x
Add 3.7 to both sides of the equal sign to get
3.7 - 7.4 = 3.7 - 3.7 + x
-3.7 = x
x = -3.7

To solve the math problem -7.4 = -3.7 + x, you need to isolate the variable x. This can be done by performing inverse operations.

First, let's start by getting rid of the -3.7 on the right side of the equation. Since -3.7 is added to x, you can subtract -3.7 from both sides of the equation to maintain its balance.

-7.4 - (-3.7) = -3.7 + x - (-3.7)

Simplifying the above equation:

-7.4 + 3.7 = -3.7 + x + 3.7

Next, perform the addition to simplify further:

-3.7 = x

The solution to the equation is x = -3.7.
