Your solutions are Y = 27 and x = 1/5
To solve systems of equations by elimination, you need to eliminate one of the variables so that you can solve for the other one. To do this, you either add or subtract the two equations. In this case, we need to subtract because both x coefficients are positive:
Y = 35x + 20
- Y = 60x + 15
0 = -25x + 5
25x = 5
x = 1/5
Now we substitute in this value of x to one of the equations and solve for Y:
Y = 35x + 20
Y = 35(1/5) + 20
Y = 7 + 20 = 27
I hope this helps! Let me know if you have any questions :)
