- What is the answer to 3x=27? | Wyzant Ask An Expert
So back to our problem, 3x = 27 All you need to do is get the x by itself, on one side of the equation So the goal is to get that 3 away from the x Suppose we took 3x and divided it by 3 Because of rule 1), we know that 3 3 = 1 So then 3x divided by 3 = 1x Because of rule 2) 1 * x = x, so 1x just becomes x this is what we wanted, x by itself!

Factor of 30 will go and make 17 if you choose 15 and 2 So you can use = 3x^2 - 2x - 15x + 10 = x(3x - 2) -5(3x-2) = (3x-2)(x-5)
- Solve the congruence, 3x-=2(mod4) | Wyzant Ask An Expert
We attempt to isolate x in 3x ≡ 2(mod 4) While we cannot attempt to divide both sides by 3, the right side can be rewritten to give 3x = 4x - x ≡ 2(mod 4) Since 4x(mod 4) ≡ 0, we have-x ≡ 2(mod 4) We can now multiply both sides by -1 to get x ≡ -2(mod 4) Adding 4 to the right side to make it positive gives x ≡ 2(mod 4)
- what is 3x-x | Wyzant Ask An Expert
3x means you have three x's Then 3x - x means you have three x's and you take away (subtract) one x This would leave you with two x's
- Whats the x intercept of y=3x-6? | Wyzant Ask An Expert
You probably already know that the y-intercept is the value of y when x=0 In this equation, is it -6
- Solve the equation 3x + 5 = 17 | Wyzant Ask An Expert
3x + 5-5 = 17-5 2 This leaves you with just the 3x on the left and the number 12 on the right 3x = 12 3 Next you must divide both sides by 3 in order to get x by itself 3x 3 = 12 3 4 After dividing, you are left with x on the left and 4 on the right x=4 Therefore to solve the equation 3x + 5 = 17, replace x with 4
- Where does the polynomial y = x + 3x + 2 cross the x-axis?
In the equation y = x + 3x + 2, we would first want to combine like terms We would now have y = 4x + 2 Since this is already in slope form, we know that 2 is the y intercept and when x = 0 then y = 2
