On Problem 2, would X not equal 20 and y equal 13?
180 = (2x+5) + 75 + (1/2)x + 50
Consolidate terms
180 = 2.5x + 130
Subtract 130
50 = 2.5x
Divide by 2.5
20 = x
Also: (2x+5) = (3y+6)
Subtract 5
2x = 3y + 1
Substitute X from above
20*2 = 40 = 3y+1
Subtract 1 and divide by 3
39=3y
13=y
I agree! Did you ever get a response to your question?
