Question

Can anyone help me with this? is equations of lines.

Answer 1

Answer: 16

Explanation:

`.\quad y=(1)/(2)x - 3\\\\\\.\quad 5=(1)/(2)x - 3\\\\.\ \underline{+3}=\underline{\ \ \quad +3}\\\\.\quad 8 =(1)/(2)x\\\\(2) 8 =(2)(1)/(2)x\\\\.\quad 16 = x`

Answer 2

x=16

Explanation:

y = 1/2 x -3

Let y =5

5 = 1/2 x -3

Add 3 to each side

5+3 = 1/2 x -3+3

8 = 1/2x

Multiply each side by 2

8*2 = 1/2x*2

16 =x
