X/4=13 4x/4=13*4 x=13*4 x=52
Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5
Lets simplify the above given equation : -8 plus 6(-x - 3) plus 4x simplified as : -8-6x -18 +4x =-2x -26 . =-2(x+13).
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
4x+13 = 21 4x = 21-13 4x = 8 x = 2
ln(4x)=13 4x=e^13 x=(e^13)/4
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13
4x + 3 = 16 Therefore, 4x = 13 x = 13/4 Therefore, x = 3.25
48-4x-13=4x+32+x First combine like terms So 48-13-4x=35-4x 4x+x+32=5x+32 Get the x by itself by subtracting the 32 from both sides 35-4x=5x+32 -32 -32 3-4x=5x +4x +4x 3=9x Divide both sides by 9 to get x by itself 3/9=x Simplify 1/3=x
9
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
4x - 7 = 45 Therefore, 4x = 45 + 7 = 52 x = 52/4 x = 13
x = 2
5x - 4x = 13 - 3 ie x = 10
x=4
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
