Question

Cansomebody help me with this Solve the following systems of inequalities using the graphing method.
Shade the solution set.

17. x+y>4
y+3x<6

Answer 1

[1] x + y = 4
[2] 3x + y = 6
y = -3x + 6
x + (-3x+6) = 4
-2x = -2
2x = 2
x = 1
// By now we know this much :
x = 1
y = -3x+6
Use the x value to solve for y

y = -3(1)+6 = 3
{x,y} = {1,3}
