Question

Y = –5x + 10
y = –3x + 2

Answer 1

Explanation:

`-5x + 10= -3x + 2` (since both equal y)

`10=2x+2` (
`+5x` both sides)

`8=2x` (-2 both sides)

`x=4` (÷2 both sides)

Sub
`x=4` to find y:

`y=-5(4)+10=-10`

Solution: x=4, y= -10

Answer 2

Explanation:

y = –5x + 10

y = –3x + 2

–5x + 10= –3x + 2

2x= 8

x=4

y= -5(4)+10

y= -20+10

y=(-10)
