How to solve |3+x| -5 = -3
Irina-Kira [14]
To solve for x, you first add 5 to both sides so it remains equal.

3 + x = 2

Then you simply subtract 3 on both sides.

x = -1

Substitute your solution into the equation and see it is true.

|3+(-1)) - 5 = -3

The equation is true, therefore your answer is: x = -1

Please help me out!​

Answer:  g = -4  and   h =1     or   g= -1  and h = -2

Step-by-step explanation:

If two exponents have the same base and are multiplied together,  you will keep the base unchange and add the exponents.  

So looking at the equation, the base is 2 for both and they are raised to the powers  g and h, meaning that if  g and h are added together they have  to equal -3.

So find two numbers that their sum is -3.

For example,  -1 and -2 add up to -3, -4 and 1 add up to -3.
