x+5=18
When you move 5 to the other side, you get x=13.
The one-step equation that equals 13 is x = 13. In this equation, x represents the unknown value that, when solved, will equal 13. This is a simple linear equation that can be solved by performing the inverse operation, which in this case would be x = 13.
1 + 12 = 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.
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.
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks

88=13+5x -13 -13 75= 5x 75/5 =15 x=15
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
The first step in solving the quadratic equation ( x^2 + 2x + 13 - 8 = 0 ) is to simplify the equation. Combine the constant terms to get ( x^2 + 2x + 5 = 0 ). Then, you can proceed to solve for ( x ) using either factoring (if applicable), completing the square, or applying the quadratic formula.

An equation demonstrates the equality of two expressions. x2+12x+13 is only one expression. For example, x+y : expression, not equation x+5 = 3 : equation
If: m/4 = -13 Then by multiplying both sides by 4: m = -52
