Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below:
4x-y=-11
2x+3y=5
A. -4x-9y=-21
-10y=-30
B. 4x+3y=5
2y=-6
C. 7x-3y=-11
9x=-6
D. 12x-3y=-33
14x=-28
*Will give brainliest answer* :-)

Answer 1

D is the answer as the both have solution x=-2 y=3
14x=-28       12(-2)-3y=-33
x=-2              -3y=-9
                       y=3
from the given equation
4x-y=11 eq 1
2x+3y=5 eq 2
x=y-11/4 from equation 1
subsitute this value of x in equation 2
2(y-11/4)+3y=5
y-11+6y=10
7y-11=10
y=3
subsitude this value of y in equation (x=y-11/4)
so x= -2 
thus same solution so ANSWER IS D
