Answer:

y=3/2x-3

y=1/8x-3/4

Explanation:

I plugged these equations into an algebra calculator, the result was this. I also did the question on edge. TRUST ME LOL

Answer:


y = (3)/(2)x - 3


y = (1)/(8) x - (7)/(8)

Explanation:

The given system is

3x-2y=6

0.4(20y+15)=x

The slope intercept form is y=mx+c.

For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6


y = (3)/(2)x - 3

For 0.4(20y+15)=x, we expand to get:


8y + 7 = x


8y= x - 7

Divide through by 8


y = (1)/(8)x - (7)/(8)

Therefore the system in slope-intercept form is:


y = (3)/(2)x - 3


y = (1)/(8)x - (7)/(8)
