8x + 5y = 22
-8x + y = 14
2 answers:
Answer:
x = -1 and y = 6
Step-by-step explanation:
-8x + y = 14
y = 8x + 14
8x + 5y = 22
8x + 5 (8x + 14) = 22
8x + 40x +70 = 22
48x + 70 = 22
48x ÷ -48 = -48
x = -1
y = 8x + 14
y = 8 (-1) + 14
y = -8 + 14
y = 6
Answer:
Y = 6 X=-1
Step-by-step explanation:
- Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
- So that means 6y=36. So Y would equal 6
- Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
- Minus 22 from both sides.
- That would give you 8x=-8
- So x would equal - 1
