Question

What is the solution to this system of equations?

18x - y = - 42

y= (-43x+34)/20

Answer 1

X=-2

Explanation:

equation a)

-y=42+18x

equation b)

y= (-43x+34)/20

Solution

42+18x= (-43x+34)/20

20(42+18x)=-43x+34

840+360x = -43x+34

360x+43x=34-840

403x= -806

x= -(806/403)

x= -(2)

x= -2
