Answer: 7x + 4 y = 2
9x - 4y= 30
-------------------
16x / = 32
x= 32:16
x=2
Step-by-step explanation: 7x+4y=2
7*2 + 4y=2
14 +4y=2
4y= 2-14
4y= -12
y= -12 : 4
y= - 3

Answer:
y = -6/7x + 16
Step-by-step explanation:
Use the slope intercept equation, y = mx + b
Plug in the slope and given point, then solve for b:
y = mx + b
4 = -6/7(14) + b
4 = -12 + b
16 = b
Plug in the slope and b into the equation:
y = mx + b
y = -6/7x + 16
So, the equation is y = -6/7x + 16

Answer: 10 years
Explanation:
The original cost of the machine = 20000
The scrap value of the machine = 13122
Value of the machine = ( 20000 - 13122 ) = 6878
Depreciation of the machine for the first year = ( 6878 * 10 % )
= 687.8
So, the effective life of the machine is = ( 6878 / 687.8 )
= 10 years
