Question

Need steps for both questions

Answer 1

`\large\boxed{Q10.\ y=2x-6}\\\boxed{Q12.\ y=-(3)/(7)x-2}`

Explanation:

The slope-intercept form of an equation of a line:

`y=mx+b`

m - slope

b - y-intercept

Q 10.

`6x-3y=18` subtract 6x from both sides

`6x-6x-3y=-6x+18`

`-3y=-6x+18` divide both sides by (-3)

`(-3y)/(-3)=(-6)/(-3)x+(18)/(-3)\\\\y=2x-6`

Q 12.

`-3x-7y=14` add 3x to both sides

`-3x+3x-7y=3x+14`

`-7y=3x+14` divide both sides by (-7)

`(-7y)/(-7)=(3)/(-7)x+(14)/(-7)\\\\y=-(3)/(7)x-2`

Answer 2

11.

6x-3y=18

-3y=-6x+18

y = (-6x +18)/-3

y = 2x - 6

12.

-3x-7y=14

-7y=3x+14

y=(-3/7)x - 2
