Hey there Chase,
Here is an example for you to practice with:
4(1-2)+2x-1=5x+1 GEMDAS then combining like terms!
4(1-2)+2x-1=5x+1 Focusing on the numbers within parenthesis. (1-2) = -1
4(-1)+2x-1=5x+1 Distribute the 4 to the parenthesis. 4(-1) = -4
-4+2x-1=5x+1
or
-4-1+2x=5x+1 Notice that -4 and -1 on this side of the equation have no x. We can
combine these like terms. Leave the number attached to an x alone
for now. -4-1 = -5
-5+2x=5x+1 Now we have -5+2x=5x+1. We need to combine like terms again! We
-2x -2x need all numbers attached to x's together and solo numbers together
on either side of the equation. We want to do the best we can to get x
all alone.
Here we subtract 2x from both sides (must do the opposite
+/- and must do to both sides always when moving to the other side of
equal sign). Subtract the 2x from the like term. This is the term with
the x. 5x-2x = 3x.
-5=3x+1 Now we have all x's combined an on one side. We want x all alone.
-1 -1 So we need to get rid of that +1 hanging on the end. We will
combine it with its like term on the other side by subtracting 1
from both sides. -5-1+-6
-6=3x Get that x all alone! Divide both sides by 3 since 3 is being
3 3 multiplied by x. -6/3=-2.
-2=x x is all alone! Hope that practice helped
