Answer:
b. (-1, 5)
Step-by-step explanation:
Since the first equation is already solved for y, we can use substitution.
Substitute y in the second equation with 3x + 8.
5x + 2y = 5
5x + 2(3x + 8) = 5
5x + 6x + 16 = 5
11x = -11
x = -11/11
x = -1
Now substitute x in the first original equation by -1 and solve for y.
y = 3x + 8
y = 3(-1) + 8
y = -3 + 8
y = 5
Answer: (-1, 5)
Answer: d. (-1,5)
Step-by-step explanation: Substitute into one of the equations, solve the equation, substitute into one of the equations, solve the equation, than write the solution.
(2,3,4,5)
The domain are all real number at x-axis
So the answer is option b (2,3,4,5)

hope it works
hi
28.5
x+y=63
x=y+23
y+23+y =63
2y +23 = 63
2y =40
y=40/2 =20
y = 20
x = 20+23=43
the numbers are 20 & 43
