First of all remeber that "a number" means we don't know the number or it could be many but not all numbers, so it is represented by x.
5. 1/2x + 6 > 20
6. 12 + 3x < -11 (They asked for the opposite of 11, the opposite of a positive number is always the negative of that number, and the opposite of a negative number is the positive of that number).
7. 2x - 8 < 5
It’s 12.5 miles per hour and the cyclist will travel 50 miles in 4 hours.
The answer is x = -3.8.
Step 1: add 7+3 (2x+10=-3x=9)
Step 2: add 3 to each side of the equation (5x+10=-9)
Step 3: subtract 10 from each side of the equation (5x=-19)
Step 4: divide by 5 on each side of the equation (x=-3.8)
