WebSubstitute that back into the solution of the original equation: x = 7 k + 4 = 7 ( 5 t + 2) + 4 = 35 t + 18 which is the required solution. If you want to express it more compactly, you can write: x ≡ 18 ( mod 35) In your answer, you've found a particular solution, but not the general one. 18, 53, 88,... etc. all solve the system. WebThe method for solving simultaneous equations with variable x and y is: First rearrange one equation to obtain an expression or a value for x. The rearranged equation may be x = a number, or it may be an expression where x = a function of y (i.e. y still exists as an unknown in the equation).
