it means 8+3x 8 increased (plus) three times a number (3x) x is an unknown number so it is often called a number

There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).
99
That gives you 11/8 of the number.
3z+4
8+3*x
Let the number be x and so the expression is: 2x+3
2x+3
you can play, just make sure to notify everyone to the missing cards
In the sequence 271217, the missing numbers can be determined by analyzing the pattern of the numbers. By looking at the sequence closely, we can see that the missing numbers are 18, 19, and 20. This is because the sequence follows a pattern of increasing by 1 from the previous number. Therefore, the missing numbers after 17 would be 18, 19, and 20 to complete the sequence.
