Question

8x + 5y = 22 -8x + y = 14

Answer 1

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 2

Answer:

Y = 6 X=-1

Step-by-step explanation:

1. Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
2. So that means 6y=36. So Y would equal 6
3. Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
4. Minus 22 from both sides.
5. That would give you 8x=-8
6. So x would equal - 1
