Answer:
Our two numbers are 50 and 20
Step-by-step explanation:
Sum means add together
Difference means subtract each other
x + y = 70
x - y = 30
subtract from each other
2x = 100
divide both sides by 2
x = 50
our first number is 50
50 + y = 70
subtract both sides by 50
y = 20
Our two numbers are 50 and 20
40x - 24 - 33x - 77 = 102
40x - 33x = 102 + 24 + 77
7x = 203
x = 29
Answer: The integer is +6
Step-by-step explanation:
This is because it say TWICE so double that and 6 added twice is 12.
SO the integer is 6 not -6 because they would cancel out and you would end up with a 0
Hope that helps
