2
Algebraic expression Solving for the variable Or X
3
There are six steps Write original equation or “WOE” Distributive property Combine like terms Pemdas backwards (+and-) Pemdas backwards ( multiply and division) Make sure the variable is isolated
4
Here’s are equation 3(5+7x)=16x
5
3(5+7x)=16x 3(5+7x)=16x 15+21x=16x -16x -16x 15+5x=0 -15 -15 5x=-15 5 5 X=-3 First let’s “WOE” Then we do distributive property we combine like terms 1 st pemdas backwards The 2 nd pemdas backwards X is isolated
6
X is isolated Here’s our answer X=-3
7
3 (5+7x-3) = 16(-3) 3 (5+-21) = -48 3 (-16) = -48 -48 = -48 the answer is right when Left = right
