You add the equations together making sure one of the variables disappears by making one negative and one positive. In this situation y would alrady disappear 8x+y=-16
(x+1)-5(x+1+3)
(x+1)-5(x+4)
x + 1 - 5x - 20
-4x - 19
Answer:
15
Step-by-step explanation:
We can find value of x using similarity ratio
(3x-5)/32 = (5x-5)/56 cross multiply expressions
56×(3x-5) = 32×(5x-5)
21x - 20x = 35 - 20
x = 15
Answer:
