x + 2x = 33 3x = 33 3x/3 = 33/3 x = 11
2x + 7 = 33 2x = 33 - 7 2x = 26 X = 26/2 X = 13
Let x = the first number, therefore x + 3 = the second number. x + (x + 3) = 33; 2x + 3 = 33; 2x + 3 -3 = 33 - 3; 2x = 30; 2x/2 = 30/2; x = 15. Hence, the answer is 15 and 18; where 15 + 18 = 33.
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
It is a linear equation in one variable, x. Oh, I suppose you want the solution? 2x + 33 = 4x + 11 Subtract 2x from both sides: 33 = 2x +11 Subtract 11 from both sides: 22 = 2x Divide both sides by 2: 11 = x
x = 59
11, you can write the question in the form of x=-2x+33, then add 2x to both sides to get 3x=33, now divide both sides by 3 and you get x=11.
If f' (x) = x43, then f(x) = (1/44) x44 + C.
3x-x44 = -41
88+x=3x+22 88=2x+22 66=2x x=33
2×11 -33 22-33 -11 1 11---1
Let the unknown number be called x: 3x-11 = x+33 3x-x = 33+11 2x = 44 x = 22 So the number is 22
