Question 536436
solve by the substitution method 
7m+n=10 
m-6n=26 --> m = 6n + 26
Sub for m in the 1st eqn
7m + n = 10
7(6n+26) + n = 10
42n+182 + n = 10
43n = -172
n = -4
-----------
m = 6n + 26
m = 2
============ 
-7x+3y=4 -2x+y=10
Solve for y in the 2nd eqn, sub into the 1st.
============
9x+8y=29 -7x+y=28
Same thing.
