Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
Equation: 5x = 65 5x / 5 = 65 / 5 x = 13

If: 2x = 26 Then: x = 13
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
88=13+5x -13 -13 75= 5x 75/5 =15 x=15
1 + 12 = WHAT
x+2y=13 has infinite answers, because you have two variables and only one equation.
Equations: 7x+4y = 9 and 2x+3y = 1 Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7 So: 14x+8y = 18 and 14x+21y = 7 Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13 By substituting y = -11/13 into any of the equations x = 23/13 Therefore the solutions are: x = 23/13 and y = -11/13

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
