Solving Equations With Variables On Both Sides Activity By Kate Equations with variables on both sides involve a few more steps, so i want to make sure you understand the simpler equations first before moving forward. let's say you have the equation below: this equation means that if you multiply a "mystery number" x by 5 and then subtract 1, the answer will be 19. to solve for x, you need to work your way. Now that all the variables are on the same side, it's a much simpler equation to solve. 12 = 5x 8 means that if you multiply x by 5 and then subtract 8, the answer should be 12. we need to solve this by working backwards and undoing the subtraction first. we can undo subtracting 8 by adding 8 to both sides. last, we can undo multiplying by 5.
Solving Equations With Variables On Both Sides Activity By Kate Since we like to avoid negatives, we'll cancel the 2x by adding 2x to both sides. this leaves us with a simpler equation that we can solve. all that's left now is to check your answer. plug in 3 for x in the original equation and make sure both sides come out to the same number. go to the next page to try a practice quiz with instant feedback. 6 (g 3) = – 2 (g 31) show video lesson. solving equations with variables on both sides. step 1: add and subtract terms to get the variables on one side and the constants on the other. step 2: multiply or divide to isolate the variable. examples: 2x 7 = 4x – 7. 3x 19 = 3 – 5x. show video lesson. Step 1. choose one side to be the variable side and then the other will be the constant side. step 2. collect the variable terms to the variable side, using the addition or subtraction property of equality. step 3. collect the constants to the other side, using the addition or subtraction property of equality. step 4. Combine like terms on each side. add or subtract like terms on both sides of the equation. 3. get all variables on one side. use addition or subtraction to move variables to one side. 4. get all constants on the opposite side. move constants to the opposite side using opposite operations. 5.
