Answer:
<u>The two numbers are 25 and 15.</u>
Step-by-step explanation:
Let's find out the two numbers, this way:
x = first number
y = second number
This is the equations system:
x + y = 40
x - y = 10
Solving for x in the first equation:
x + y = 40
x = 40 - y
Solving for y in the second equation:
40 - y - y = 10
40 - 2y = 10
-2y = 10 - 40
-2y = - 30
<u>y = -30/-2 = 15</u>
Solving for x:
x + y = 40
x + 15 = 40
x = 40 - 15
<u>x = 25</u>
<u>The two numbers are 25 and 15.</u>
Answer:
60
Step-by-step explanation:
ingressos: 55 x 2 = 110
25 x 2= 50 Tax
110+50=160 total
160-100= 60
