Given the equation y = 3x − 4, what is the value of x when y = 5? A) 3 B) 6 C) 9 D) 12
Dmitrij [34]

Answer:

A. 3

Step-by-step explanation:

The answer would be A because 3 times 3 is 9 and 9-4=5 which is the value o f y. 3x-4=5

add 4 to both sides: 3x=5+4

simplify: 5+4=9

divide both sides by 3:  x= 9/3

simplify 9/3 to 3:

x= 3

hope this helps!!

What is the solution to the equations x^2-2x+y=8 and x-y=-2
kherson [118]
Hello!!

For the first equation:

-2x + x^2 + y = 8   (Solve for y)

y = -x^2 + 2x +8

For the second equation:

x - y = -2   (Solve for y)

-y = -x - 2

-y = x + 2

Good luck :)
