Solve the system by substitution.

As we know y=3/4x-3
Let's put it in the second equation
3/4x-3=1/4x+1
3/4 x -1/4 x = 1+3
2/4 x = 4
X= 4*4/2
x=8
Put x= 8 in first equation
y= 3/4 *8 -3
y=6-3
y=3
Check the answer
3=3/4 *8 -3
3=6-3
3=3
Correct
So(y, x) = (3,8)
Because x=8 and y=3

Write an appropriate direct variation equation if y = 18 when x = 2

Sergeu [11.5K]

Answer:

$y=9x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In this problem we have

y=18 when x=2

Find the value of the constant of proportionality k

$k=\frac{y}{x}$ ----> $k=\frac{18}{2}=9$

therefore

The equation is equal to

$y=9x$
