yes i agree with her because elimination method is more simpler and shortest method to solve system of equations.
elimination method use to multiply of both equation in order to balance the variable x or y and then equate them.
example
x+2y=7 .....equation 1
x-3y=14 .......equation 2
so you can multiply equation 1 by -1 in order to equate x and get the value of y by saying equation 1 minus equation 2.

Step-by-step explanation:
Answer:a : 22.6 b: 42
Step-by-step explanation: add up all your numbers then you divided by the number of digits you have for example:
10 4 1 add these numbers and you got 15 now you divided by three because there are three numbers so it's 5 because 15 div by 3 is 5
13 x 85 = 1105
78 + 91 = 169
169 / 1105 = 6.5
Answer:40/50= 0.8 or 80% did not pick science
