Question

4x + 6y = 12

2y = 4x + 20
btw its Elimination for 8th grade so pls get this answer right!

Answer 1

(1): 4x + 6y = 12: x-intercept: (3, 0), y-intercept: (0, 2).

(2): 2y = 4x + 20: x-intercept: (-5, 0), y-intercept: (0, 10).

Explanation:

Hope this helps =)

Answer 2

y = -2; x = 6

Explanation:

First what you need to do is change the formatting of the second equation.

So it would be:

4x + 6y =12

4x - 2y = -20

Now that the equations are correct, just subtract the x values, y values, and whole numbers. You'll get 4y = -8 -> y = -2

Next, you'll plug in that y value into one of the equations to get the x value.

4x + 6(-2) = 12

4x + -12 = 12

4x = 24

x = 6

Therefore, the values are y = -2 and x = 6 :)
