Now that we have one of the variables from Part A isolated, and w the two original equations. Which of the following options represents this? tten in terms of the other variable, we can now subsfiute this into the other of
2A + 3(3A-5)=4
2(B + 5) + 3B =-4
O 2A+3(-5)=4

2A + 3(3A - 5) = -4

Step-by-step explanation:

from the B part

2A + 3B = -4

where B =3A - 5

Substitute into the above equation;

2A + 3(3A - 5) = -4

2A + 9A - 15 = -4

11A = -4+15

11A = 11

A = 1

Put A = 1 in B = 3A - 5

B = 3(1) - 5

B = -2

The values are 1 and -2
