Question

solve the equation using reverse order of operations1. x - 4 = -22. a + 10 = -4 3. 59 =s + 90

Answer 1

We want to slove the given equations using reverse order of operation

1. x - 4 = -2

Reverse subtraction of 4

x - 4 + 4 = -2 + 4

x = 2

2. a + 10 = -4

Reverse addition of 10

a + 10 - 10 = -4 - 10

a = -14

3. 59 = s + 90

Reverse addition of 90

59 - 90 = s + 90 - 90

-31 = s

s = -31
