Question

Some steps in solving an equation are more efficient than others. Complete parts (a) though (d) to determine the most efficient first step to solve the equation 34-5x=-21

Answer 1

The solution of the given equation x =11

Explanation:

Given equation 34 - 5x = -21

Step :-(a)

Given equation 34 - 5x = -21

Subtracting '34' on both sides , we get

34 - 5x -34 = -21 -34

Step:-(b)

on simplification , we get

-5x = -55

Step:-(c)

Dividing ' -5' on both sides , we get

`(-5x)/(-5) =(-55)/(-5)`

Cancellation '-5' on both sides , we get

x = 11

Step :-(d)

The solution of the given equation x =11
