Answer:
(4, 5)
Step-by-step explanation:
y = 2x - 3
y = 7 - 0.5x
y is already isolated on both equations, set them equal to each other:
2x - 3 = 7 - 0.5x
add 3 to both sides:
2x = 10 - 0.5x
add 0.5x to both sides:
2.5x = 10
divide by 2.5:
x = 4
plug in 4 for x on either equation and solve for y:
y = 2(4) - 3
y = 8 - 3
y = 5
