6-124 (Review: Equations) Some steps in solving an equation are more efficient than others. Complete parts (a) through (d) to determine the most efficient first step to solve the equation 34 = 5x - 21 a. If both sides of the equation were divided by 5, then the equation would be make the problem simpler? Why or why not? 34/5 = x - 21/5 Does this b. if you subtract 34 from both sides, the equation becomes 0 = 5x - 55 Does this make the equation simpler to solve? Why or why not? c. if you add 21 to both sides, the equation become 55 = 5x Does this suggestion make this a problem you can solve more easily? Why or why not?
