2-step Equation • definition of equation- an equation says that two things are the same, using mathematical symbols. • Like +,-,x,/,=
2-step equations Example of an Equation 5x+2=7
2-step equations How to solve the equation. 2x - 1= 3 step 1: change the subtract sign to a plus sign step 2: then you add 3+1=4 step 3: then you are left with 2x=4 step 4: then you divide both sides by 2 step 5: then you get the answer is x=2 step 6: then you check and see if that answer of the question if it works
2-step equation And this is how we work the 2-setp equation And I want you to try it for math.
