If 19 is half (50%) of something, find that number you would just have to multiply 19 by 2.
This means that 19 is 50% of 38.
Solve this equation: $45 - ($2.75/pen)x = $12. Simplifying, we get
$33 = ($2.75)x, so that
x = $33 / ($2.75) = 12.
Tim's buying 12 pens leaves him with $12.
Answer:
x = 80
Step-by-step explanation:
The whole reason algebra exists is to solve for a variable. Therefore, the only way to get x by itself or to see what x equals is to subtract 20 from both sides. Doing this will make x be all alone on one side of the equation and to see what x is.
x + 20 = 100
x + 20 -20 = 100 -20
x = 80
