Answer:

x=3

Explanation:

Hey there!

In order to solve this equation, we must first distribute the 3

3x + 9 = -4x + 30

Now we combine like terms

7x = 21

Then we divide both sides by 7 to get x by itself

x = 21/7

x = 3

Answer: x=3

Explanation:

To solve the given equation, it means to find the value of x. We want to use inverse properties to isolate x. The inverse properties are add/subtract and multiply/divide. Be sure to use the corresponding inverse operation.

3(x+3)=-4x+30 [distribute]

3x+9=-4x+30 [add both sides by 4x]

7x+9=30 [subtract both sides by 9]

7x=21 [divide both sides by 7]

x=3

Therefore, we get x=3.
