Normally you would need the remainder of the equation to solve it. However, anything times one equals itself, so the answer (in part) is "2y". Remember, you can't solve the equation fully without finding the value of 'y', and you cannot find the value of 'y' unless you know what resides on the other side of the equal sign.

What is .323232 as a fraction?
You solve this as follows. You call your number "x", and write:x = .323232... (equation 1) Then you multiply this equation by 100 (a one, followed by two zeros - this is because the length of the period is 2), and get: 100x = 32.323232... (equation 2) Now you can subtract equation 1 from equation 2, and solve for "x". This will give you "x" as a fraction.
How do you do math substitution?
Mathematical substitution is the process of using one equation to solve for multiple variables. For example: Equation 1: x + y = 4 Equation 2: 2x + y = 16 Using equation 1, solve for y: y = 4 - x <-- Plug this into equation 2. This is substitution because you are replacing y in equation 2 with what y is equal to in equation 1. 2x + y = 16 ----> 2x + (4 - x) = 16 Now you can solve for x: x + 4 = 16; x = 12 You can then substitute the value of x back into the equation that is solved for y: y = 4 - 12; y = -8 Check both equations: Equation 1: -8 + 12 = 4; 4 = 4 (Correct) Equation 2: 2(12) + (-8) = 16; 24 - 8 = 16; 16 = 16 (Correct) We have successfully used substitution to solve for two different variables, x and y.
What times 6 equals 2?
To solve the equation "6x = 2," you need to isolate the variable x. To do this, you would divide both sides of the equation by 6. Therefore, x = 2/6, which simplifies to x = 1/3. So, the value of x that satisfies the equation "6x = 2" is 1/3.
Can you solve 3x2-x equals -1?
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
What is a 2 step equation that equals 13?
A 2-step equation that equals 13 could be: 2x + 7 = 13. To solve this equation, first subtract 7 from both sides to isolate the variable: 2x = 6. Then, divide both sides by 2 to solve for x: x = 3. Therefore, when x = 3, the equation 2x + 7 equals 13.
