I’m having trouble finding the answers to this problem

Mathematics

slamgirl [31]2 years ago
3 0

Step-by-step explanation:

Solve by Subsitution

x = 50 - y

Replace this into the second equation

y(50 - y) = 300

50y -  {y}^{2}  = 300

Write in standard form

-  {y}^{2}  + 50y = 300

Use the quadratic formula, and our answer will be

(6.97,43.02)

(43.02,6.97)
