1- and 2-Step Equations

1-Step

100

how do you solve 1-step equations?

To solve the one-step equations, isolate the variable by doing the reverse operation for the equation. So, if the variable is added with a number, subtract the number on both sides to isolate the variable. Similarly, do addition for a subtraction equation X-4=7 +4 +4 X=11 CHECK! 11-4=11

200

X-4=7

X-4=7 +4 +4 X=11 CHECK! 11-4=11

What do you do when the coefficient is negative in an inequality?

Flip the sign.

200

-2x + 4 < 12

x > -4

One-step equations

 Undo subtraction by adding to both sides or undo addition by subtracting on each side. Do the same for multiplication and division

200

2-step equations

 solve the subtraction and addition left to right. Then do the multiplication/division. Then check
