Answer:

(2,1)

Step-by-step explanation:

y = -x + 3

so sub in -x + 3 for y back into the other equation

x + 4y = 6

x + 4(-x + 3) = 6

x - 4x + 12 = 6

x - 4x = 6 - 12

-3x = -6

x = -6/-3

x = 2 <====

y = -x + 3

y = -2 + 3

y = 1 <=====

solution is : x = 2 and y = 1....or (2,1)

Answer:

x = 2

y = 1

Step-by-step explanation:

x + 4y = 6

y=-x+3

first ,we substitute y by -x+3 in the first equation then we get:

x + 4(-x+3) = 6

y=-x+3

then

x - 4x + 12 = 6

y=-x+3

then

-3x = 6 - 12 = -6

y=-x+3

then

x = 2

y = -2 + 3 = 1
