Find the number of ordered pairs (m,n )which satisfy the system

4(m-n)=7(1-n),

(3/2)n=4-2m

First clean up your equations by expanding and simplifying

4m-4n=7-7n

4m +3n = 7

3/2 n = 4 - 2m

4m + 3n = 8

Both the same equation but they equal different constants.... there is NO SOLUTION....prallel lines do not cross/intersect.
