14x2 + 15x + 4 = (7x + 4)(2x +1)
-6x
The sum of fifteen times a number and eight.
-7x + 6 + 7x - 2 = 4
I think the question is asking "what value of y satisfies the equation 15x + 15y = 15x + y ? " If so, the answer is y = 0.
14x2 + 15x + 4 = (7x + 4)(2x +1)
6x - 14 + 15x + 2 =21x - 12or3 (7x - 4)
7x-9
-x - 2 + 15x = 14x - 2 = 2(7x - 1)
It is 15x -24 when simplified
x = 4 You have to add the 8x and 7x to get 15x and then divide 60 by 15 to get x by itself.
-6x
7x + 3 = 15x + 97x+3 = 15x+9 7x-15x = 9-3-8x = 6x = -6/8 => -3/4Explanation of working out the problem:7x+3=15x+9We want X's on one side and numbers on opposite side of Equal.When we move from one side to another, we also replace + with - and vice versa.7x-15x=9-3-8x=6We divide both sides with 2 so that we get a smallest possible answer.-4x=3I hate dealing with negative X's. it is so... negative..Multiply both sides with -1 and you get:4x=-3If you need to find X alone, then divide by 4 on both sides.x=-3/4 or in decimal terms it will be:x=-0.75And that is the end of the story :-)
It is -9x plus 5.
-119 - 7x = 8x + 16Add 7x to each side of the equation:-119 = 15x + 16Subtract 16 from each side:-135 = 15xDivide each side by 15:-9 = x
168x3 - 45x2 + 3x = 3x(56x2 - 15x + 1) = 3x(7x - 1)(8x - 1)
(7x-3y) + (2x+5y) = 9x+2y
