Question

Solve this system of equations. y=11-2x 4x-y=7 x=___ y=___

Answer 1

x=3

y=5

Explanation:

y=11-2x equation 1

4x-y=7 equation 2

using equation 1 in equation 2 we have:

4x-(11-2x)=7

4x -11 +2x =7

6x -11 =7

6x = 7+11

6x= 18

x= 18/6

x=3

so we have:

y=11-2x

y= 11-2(3)

y=11-6

y=5
