Answer:
4x-3y=-10 ans C
2x+3y=4
Step-by-step explanation:
4x-3y=-10--------eqn 1
2x+3y=4----------eqn 2
multiply eqn 1 by 2 and eqn 2 by 4
8x-6y=-20
8x+12y=16
subtract eqn 2 from 1
8x-8x ,12-(-6y)=16-(-20)
18y=36
divide both sides by 18
y=2
substitute y=2 in eqn 1
4x-3(2)=-10
4x-6=-10
4x=-10 + 6
4x= -4
divide both sides by 4
x= -1
