Question

What is y - 4x = 15 * y = 6x + 11 *

Answer 1

Answer:

x = .4

Step-by-step explanation:

I honestly don't know, I tried though.

Answer 2

It’s a simultaneous equation

So first find x


(A) Y - 4x =15
(B) Y - 6x = 11 (rearranged)

(A) - (B)

2x = 4
x=2


Use x to find y

Y - 4x = 15

Y - (4*2) =15

Y - 8 =15

Y = 23

Check if values for x and y are correct

Y - 6x = 11

23 - (6*2) = 11

23 - 12 = 11 (so yes it’s right)


Therefore
X=2
Y=23

Hope this helps!
