Correct the first way is 1to1, 1:1, 1 boy to 1 girl .
Answer:
<em>B. </em>
<em></em>
Step-by-step explanation:
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
