You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.
The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.
In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.

How do you solve the equation x-7y equals 3?
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
How would you solve this 9x - 3 6?
l9xl - 3 > 6 Is the equation.
How do you solve the equation -3x minus 5 equals -20?
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
How do you solve the equation 3x-2 equals 2x plus 3?
3x-2 = 2x+3 3x-2x = 3+2 x = 5
A system of linear equations with an infinite number of solutions?
This can happen in different ways: a) More variables than equations. For instance, a single equation with two variables (such as x + y = 15), two equations with three variables, two equations with four variables, etc. b) To of the equations describe the same line, plane, or hyper-plane - this, in turn, will result in that you "really" have less equations than it seems. For example: y = 2x + 3 2y = 4x + 6 The second equation is simply the first equation multiplied by 2.
