Answer:
the system has no solutions
Step-by-step explanation:
substract both equations and the result will be:
y - y = x - x + 2 + 1
0 = 3 is incompatible, so, no solution
C. 4x + y = 21
4(3) + 9 = 21
12 + 9 = 21
21 = 21
90/2 is 45.. 60/2 is 30.. 30+45=75... 75 students would be able to be in each of the 2 groups, each containing 45 girls and 30 boys ... Hope I helped (:
