Answer: x= -2 and y= 4
Explanation:
Let's solve your system by substitution.
2x+y=0;5x+3y=2
Step: Solve 2x+=0 for y:
2x+y=0
2x+y+−2x=0+−2x (Add -2x to both sides)
y = −2x
Step: Substitute −2x for y in
5x+3y=2:
5x+3y=2
5x+3−2x=2
-x=2 (Simplify both sides of the equation)
−x/−1=2/-1 (Divide both sides by -1)
x=−2
Step: Substitute −2for x in y=−2x:
y=−2x
y =(−2)(−2)
y=4 (Simplify both sides of the equation)
Answer:
x=−2 and y=4
