Use substitution to solve 1-2.<br><br> 3x – 3y = 9<br> x= 7 – 3y
kondaur [170]

Answer:

Solutions are x =4 and y = 1

Step-by-step explanation:

3x-3y =9

In this equation substitute x=7-3y, we get

3(7-3y) -3y=9\\21-9y-3y=9\\-12y= 9-21\\-12y= -12\\y=1

now substitute y =1 in x equation,

x=7-3(1)\\x=7-3\\x=4

Solutions are x =4 and y = 1
