Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation:
simplify it :
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
Answer:
y = 8
Step-by-step explanation:
y= + 6
= -6
y=( x 6) + 6
y= 2+6 = 8
Hope this helps you!
