Help and explain !!!!( Solve using the substitute method )
alex41 [277]

Answer:

x=13

y= -9

(13, -9)

Step-by-step explanation:

If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.

Then, we can take that equation and plug it into the bottom one so

3x+4(4-x)=3

Simplify:

3x+16-4x=3

-x=-13

x=13

We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)

So, 13+y=4 which y= -9

Maru [420]

Answer:

y-3 = 4/7(x-7)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)

We know the slope (4/7)

and a point (7,3)

Lets substitute into the equation

y-3 = 4/7(x-7)
