To solve the equation "twice the number plus seven is equal to three less than four times the number," we can express it mathematically as ( 2x + 7 = 4x - 3 ). By rearranging the equation, we get ( 7 + 3 = 4x - 2x ), leading to ( 10 = 2x ). Dividing both sides by 2 gives ( x = 5 ). Thus, the number is 5.

Thirty decreased by three times a number is six less than three times the number. Find the number.
2 and three halfs
Let the number be x: 7x < or = to 6x-2 7x-6x < or = to -2 x = -2
The real answer is n-7
3x - 7 ≤ 9 "Seven less than" means that you subtract seven from the answer. "Three times a number" means that you multiply it. "At most" means that this is the greatest number that it can be, which is, in this case, 9. To solve this, you apply the principle rules of algebra to determine x. 3x ≤ 9 + 7 3x ≤ 16 x ≤ 16/3
If seven times a number results in 35, then six times a number would be five less.
two less than three times a number is 28
seven seven
Five (5) more than (+) three times a number (3x) is (=) five times the number (5x) less (-) three (3) 5 + 3x = 5x - 3 x = 4
Three times a number is 10 less five times the number can be put in the form of an equation that looks like this: 3x = 5x-10. Now just solve for x...

numbe is 5
Let the number be x and if you mean: -3x+7 = -11 then the value of x is 6
