Question

Find the x and y intercepts. Write your answer as x =
y =
10x + 5y = 120

Answer 1

y=2× -24

Explanation:

-5y=-10× +120

-5y/-5=10×/-5 +120/-5

y=2× -24

Answer 2

x = 24 - y / 2

y = 2(-x + 12)

Explanation:

Solving for x:

10x + 5y = 120

-5y -5y

-------------------------

10x = 120 - 5y

/10 /10

-------------------------

x = 24 - y / 2 (write 24 - y at the top of the fraction and 2 in the bottom)

Solving for y:

10x + 5y = 120

-10x -10x

------------------------

5y = 120 - 10x

/5 /5

-------------------------

y = 120 - 10x / 5

Factor 120 - 10x

= 10(12 - x)

Now divide by 5

y = 2(-x + 12)
