Question

2.) Solve each equation by subtracting a number from each side to isolate x.

a.) x+5= 12
b.) 15= x+6
c.) 19= 7+x

Answer 1

Hey there, Lets solve this problem together.

Equation (A) =
`x+5= 12`


`x + 5 - 5 = 12 - 5 x = 12 - 5 x = 7`

Equation (B) =
`15= x+6`


`15 - 6 = x + 6 - 6 15 - 6 = x 9 = x`

Equation (C) =
`19= 7+x`


`19 - 7 = 7 - 7 + x 19 - 7 = x 12 = x`

Answer 2

a) x+5= 12

x + 5 - 5 = 12 - 5
x = 12 - 5
x = 7

b) 15 + x + 6
15 - 6 = x + 6 - 6
15 - 6 = x
9 = x

c) 19 = 7 + x
19 - 7 = 7 - 7 + x
19 - 7 = x
12 = x
