Here is a system of two linear equations. x+y=4
2x + 3y = 18
The x value of the solution to the system of equations is
-10
-6
2
10

x=2

Step-by-step explanation:

x+y=4->x=4-y

2(4-y)+3y=18

8y-2y+3y=18

9y=18

y=2

x=4-y x=4-2 x=2

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:
