x equals 19
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
7
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
An equation where x equals 3.
(2, 3)
7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
6x+13=-2x-19 so 8x=-19-13=-32 so x=-4
1 + x + 2x = 20 So 1 + 3x = 20 so that 3x = 19 then x = 19/3 or 61/3
it equals 13X.
