5(x-3y)-2x=6 and x=3y
Solve the equations please by substitution

Answer for the first equation:

(7, -1)

Step-by-step explanation:

Original Equation: 5(x - 3y) - 2x = 6 When x = 3y

Substitute in the 3y for x:

5(3y - 3y) - 2(3y) = 6

5(0) - 6y = 6

-6y = 6

y = -1

Plug -1 in for y in the original equation:

5(x -3(-1)) - 2x = 6

5(x + 3) - 2x = 6

5x + 15 - 2x = 6

3x + 15 = 6

3x = -9

x = -3

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
