Question

Help find out what the x is please

Answer 1

When we're solving for a variable, we need that variable alone on one side. To do that, we'll get rid of that 8.8.

It's being subtracted from 4x, so to cancel it out, we'll add 8.8 to bring 4x back to its normal amount. What you do to one side, you do to the other, so we have to add 8.8 there too.

7.2 = 4x - 8.8
+8.8 ----- +8.8


16 = 4x

Now, to find out what one x equals, we have to divide 4x by far. We must also do this to the 16 to keep the equation balanced.

16÷4 = 4

4 = x

Let's plug that into the equation and check out work.

7.2 = 4 (4) - 8.8

7.2 = 16 - 8.8

7.2 = 7.2

Hope this helps!

Answer 2

Answer:

x=4

Step-by-step explanation:

First you want to add 8.8 to 7.2 and get 16 because you want to get x alone

Next divide divide 4x on both sides so 4x/4x cross out and left with just x. 16/4 =4

x=4

Hope this helps!
