Answer:
The solution is (22.8, 40.1)
Step-by-step explanation:
Transform the equations to 'y = '
2r + 3y = 169
3y = -2r + 169
y = -2/3 r + 169/3
5r = y + 74
y = 5r - 74.
Now you can use the calculator to draw the graphs or use the equation facility if it has one.
Where the graphs intersect is the solution.
9514 1404 393
(r, y) = (23, 41)
See the attachment for the solution.
