Answer:
b=c-ax/y
Step-by-step explanation:
1) ax + by = c
-ax
2) by = c - ax

4) b = c-ax/y
Answer:
the answer is r<1 that's the inequality
3(2m + 9) - 1 = 2
6m + 27 - 1 = 2
6m + 26 = 2
6m = 2 - 26
6m = -24
m = -4
Solve for the first variable in one of the equations, then substitute the result into the other equation.
3. (1/2, -1,2)
4. (2, -4)
