Question

Solve the system of equations without graphing. Show your reasoning. 2y=x-4 4x + 3y = 5

Answer 1

Answer:

x=2 and y= -1

Step-by-step explanation:

1) we transform first equation

2y= x-4

2y +4= x

So x= 2y+4

2) we insert equation from 1) into second equation

4*(2y+4)+3y=5

8y+16+3y=5

11y+16=5

11y= -11

y= -1

3) insert y into 1)

x= 2*(-1)+4

x= -2+4

x= 2
