Question

solve x+0.5y=10 using graph​

Answer 1

Answer:

10 - 0.5y = 1.5x

-1.5x - 0.5y = -10

Multiply both sides by -2:

Eq1: 3x + y = 20

y = 0.5(6x+40)

y = 3x + 20

Eq2: -3x + y = 20

Add Eq1 and Eq2:

2y = 40

Y = 20

In Eq1. replace y with 20:

3x + 20 = 20

3x = 20-20 = 0

X = 0.

Solution Set: (x,Y) = (0,20).
