Solve the system of equations.<br> ​ 7x−3y=20<br> y=5x−4<br> x=<br> y=<br> ​
Ksenya-84 [330]

Answer:

Step-by-step explanation:

substitute the value of y in the first equation.

7x-3(5x-4)=20

7x-15x+12=20

-8x=20-12

x=8/-8

x= -1

then you substitute the value of x on the y equation to find y

y=5×-1 -4

y= -5-4

y= -9
