the equation is 2x + 4 = x - 3
solving it yields x = -7
Four more than twice a certain number ( x ) can be expressed mathematically as ( 2x + 4 ). This means you first multiply the number ( x ) by 2, and then add 4 to the result.
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.

If we let the number be represented as ( x ), then twice the number can be expressed as ( 2x ). Adding 4 to this gives us the expression ( 2x + 4 ). Therefore, 4 more than twice a number is ( 2x + 4 ).

If a "certain number of men" less 10 takes 20 days (twice as long) to finish the piece of work, then the "certain number of men" who can finish the work in 10 days would 20. If it takes 10 men less twice as long to do the work, then twice 10 men (20) can finish the job in 10 days.
Four more than twice a certain number ( x ) can be expressed mathematically as ( 2x + 4 ). This means you first multiply the number ( x ) by 2, and then add 4 to the result.

2x + 4 < x x < -4
Twenty more than twice a number is 52
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
Example:VERBAL SENTENCE:Seven more than twice a number is four less than thrice the number.MATHEMATICAL EQUATION:(seven more than) (four less than)(twice a number) is (thrice a number)2x + 7 = 3x - 4=Earljoyce8♥=Hope this helps!!
14 more then a number cubed minus twice the number
X = number. 4X + 9 = 2X - 15 ===========

2x-3=x+2 answer x=5
