Answer:
1200
Step-by-step explanation:
n = 0.08 r + 7400
n = 7496, r = ?
7496 = 0.08r + 7400
7496 - 7400 = 0.08r
96 = 0.08r
r = 96/0.08
r = 1200
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
