Since x = y + 2

so
y + 2 + 4y = 7

5y + 2 = 7

5y = 7-2

5y = 5

y = 1

x= y + 2

x = (1) + 2

x = 3

(x,y) = (3,1)

If g(x)=2x+1 and h(x)=x-2 then find (g-h)(x)

qwelly [4]

(g-h)(x) = 2x+1 -(x-2)
(g-h)(x) = 2x+1 - x + 2
(g-h)(x) = x + 3

How do you do this? Please help, I’ve been staring at this for like 10 min :)

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

$x=-2\\y=2(-2)+5\\y=-4+5\\y=1$

------

$x=-1\\y=2(-1)+5\\y=-2+5\\y=3$

------

$x=0\\y=2(0)+5\\y=0+5\\y=5$

------

$x=1\\y=2(1)+5\\y=2+5\\y=7$

------

$x=2\\y=2(2)+5\\y=4+5\\y=9$
