What are the rules to solving equations by multiplying or dividing?
Andreas93 [3]

Answer:

In order to move a number that is multiplied or divided by the variable, make sure to inverse both sides! That means, if the number is multiplied, you divide it by both sides. If it's divided, you must multiply it by both side; steps so that you can apply them to harder equations.

Sorry if this didn't help! I hope it did though, good luck. <3
