Step: Solvey=2x+13for y:
y=2x+13
Step: Substitute2x+13foryinx−y=4:
x−y=4
x−(2x+13)=4
−x−13=4(Simplify both sides of the equation)
−x−13+13=4+13(Add 13 to both sides)
−x=17
−x−1=17−1(Divide both sides by -1)
x=−17
Step: Substitute−17forxiny=2x+13:
y=2x+13
y=(2)(−17)+13
y=−21(Simplify both sides of the equation)

(-17,-21)
Answer:
x = 8; y = 2.5.
Step-by-step explanation:
As we know , when two complex numbers are equal their real as well as imaginary part are equal.
So comparing on both sides ,
2x = 16 and 5 = 2y
x = 8 and y = 2.5.
So , x = 8; y = 2.5.
Answer:
k12
Step-by-step explanation:
Answer:
Yes I think
Step-by-step explanation:
Take the square root of both sides to get rid of parenthasees, remember to get the positive and negative root
5x-2=+/-√10
add 2 to both sides
5x=2+/-√10
divide by 5
