Answer:
x = -5
Step-by-step explanation:
7 × 2 + 5 - x = 6 × 2 + 10
Multiply.
14 + 5 - x = 12 + 10.
Combine like terms.
19 - x = 24
Isolate x (I'm going to add x and subtract 24 from both sides to avoid changing signs)
-5 = x
Final answer
x = -5
All odd numbers have an even number on either side of them. All even numbers are divisible by 2. So all odd numbers can be represented by the expression 2x+1 where x is any integer. Let another odd number be 2y+1.
Now subtract one from the other: 2(x-y), the ones cancel out. No matter what x and y are, their difference is doubled, making it even, therefore the difference between two odd numbers is always even.
