Disney Math Workbook…How To Solve Equations By: ordan Niedoba
How To Solve One-Step Equations To solve a one-step equation, do the inverse operation to both sides in order to get the variable by itself. Remember to check your solution Example:4x=124 4=x 124=32 Check:4x+124 4 x 32=124 X=124 4
How To Solve A Two-Step Equations To solve a two-step equation, first, divide your problem by the equal sign. Next, circle your variable. Third, get rid of the number next to the variable by using addition or subtraction. Finally, multiply or divide. Example: x-7=-9 7+7=x -9+7=-2 x=-2 5 x 5=x -2 x 5=-10 Check: x-7=-9 -10-7=-9 -2-7=-9 x=-10 5 5
