The answer is x = 19.
(I'm assuming that in this equation, you need to solve it by finding x.)
By following PEMDAS, you would need to
multiply the 2.25 into the (4x-4)
.
9x -9 = -2 + 10x + 12
You then
subtract the 9x into the 10x
, which limits the factor to one side of the equation.
-9 = - 2 + x + 12
Following that, you need to move the other components so to find the value of x. You do that by
adding 2
to each side to nullify the
-2
on the
x side
.
-7 = x + 12
Then you
subtract 12
from each side to nullify the
12
on the
x side
.
-19 = x
Hope this helps!
