X=17-4y<br> y=x-2<br> answer by substitution
sashaice [31]

Answer:

x=5,y=3

Step-by-step explanation:

the first step is to decide whether you want to substitute y and find x, or substitute x and find y.

(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).

for example, let's substitute y into the first equation:

x=17-4*(x-2)

so now,we will organize the equation:

x+4x=17+8

5x=25/(÷5)

x=5

now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:

y=5-2

y=3
