X is minus 2
y is equal to 1
The second answer is D) it will increase 8 times
Answer:
D (-6, -34)
Step-by-step explanation:
y = 5x - 4
Let x = -6
y = 5(-6) - 4
=-30 -4
= -34
x = -6, y= -34

Answer:
x=0, y=-5
Step-by-step explanation:
The system is
(1) 5x+3y=-15
(2) -8x-2y=10
Let's solve it by elimination. In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated
Multiply (1) by 2 and (2) by 3
(1) 10x+6y=-30
(2) -24x-6y=30
Add the two equations
10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0
Now replace this value in any equation, for example in (1)
6y=-30 ----> y=-30/6----> y=-5
