X= a number making both expressions equivalent since the picture shows them being equal.
1st : We will move the terms.
Note: (anything moved to the other side of the equal sign will change signs)
2nd : Calculate,
1x = x
Meaning 1x and x are the same meaning,
Now, we must calculate with x being 22...
Solve by multiplying first then subtracting,
This means 5x - 20 = 90 and if the two expressions were equivalent then 4x + 2 should also equal 90 yet let's check...
Solve by multiplying first then subtracting,
So both expressions equal 90.
Finally, let's calculate 2x + 6 with 22 as x,
Solve by multiplying first then subtracting,
