Solve using double substitution y=x-7 y=-2x+8

Mathematics
1 answer:
Ivenika [448]3 years ago
8 0

Answer:

(5, -2)

Step-by-step explanation:

x - 7 = -2x + 8

add 2x to both sides

x - 7 + 2x = -2x + 8 + 2x

3x - 7 = 8

Add 7 to both sides

3x - 7 + 7 = 8 + 7

3x = 15

3x = 15

x = 5

y = 5 - 7

y = -2


Solution (5, -2)
