Question

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. y=4x and 3x+2y=55 *

Answer 1

(5,20)

3x + 2(4x) = 55
3x + 8x = 55
11x = 55 / 11
x = 5

4(5) = 20
y = 20

Answer 2

(5,20)

Explanation:

Because 3x+2(4x)=55 is then 11x=55, then divide the both by 11 to get x=5

The substitute y=4(5) because of x the get y=20
