Let the unknown number be x and so the expression is: 2x-3
3-x
The number is 7.
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
3a-6x2
Let the number be x and so if 2x-3 = 13 then the value of x works out as 8
twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2
As an algebraic expression this is written 2x - 12, where x is the unknown number.
3-x
Thrice A number divided by five is three
x + x - 3 = 2x - 3
Let the unknown number be x and so the algebraic expression is: 2x -13
The number is 7.
The number could be -12.5326 or 10.5326 (approx).
sum - means addition less - means subtraction twice - means multiply by 2
The expression can be thus: 3x-3 whereas x is the unknown variable
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
