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)).

The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).

I'm not clear on what you're asking here, but if you want that written as an equation, it is: 2x - 3
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

the sum of three numbers is 64. the second number is 3 less than the first number, the third number is 11 less than twice the first. what are the three numbers?

This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
twice the difference of three times a number and eight
