Answer:
Step-by-step explanation:
Are you sure you wanted that "b" in the second equation?
If so, here's how we eliminate y:
1) Multiply the first equation by b: 8bx + 3by = 2b
2) Multiply the second equation by 3: 12x - 3by = -21
3) Combine these two results. We get:
(8b + 12)x = 2b - 21
Here we have eliminated y, but still have an equation in two variables, b and x.
Answer:
Step-by-step explanation:
(x - 3)/2 = 9
x - 3 = 18
x = 21
(y - 5)/2 = 6
y - 5 = 12
y = 17
(21, 17)
