Chapter 0.5, Problem 25E

To determine

To solve the equation $-2y+17=-13$

Answer to Problem 25E

  $y=15$

Explanation of Solution

Given Information: $-2y+17=-13$

Formula Used : Linear equations with one variable

Calculation:

Given equation is

  $-2y+17=-13$

To isolate the variable y, adding 13 both sides-

  $-2y+17+13=-13+13$

This gives-

  $-2y+30=0$

To isolate the variable y, bring 30 to otherside-

  $-2y=-30$

To simplify further, multiply by (-) both side-

  $2y=30$

To isolate the variable y, divide by 2 both side-

  $\frac{2}{2}y=\frac{30}{2}$

Hence the final answer is-

  $y=15$
