12 + 5 equals...
To solve for x, we'd have to know what this expression equals.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s

You need two independent linear equations to solve for two unknown variables.
If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
X +13 equals 22, X equals nine
12 + 5 equals...
To solve for x, we'd have to know what this expression equals.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution. The most that you can do is: 13p = 31-7k so that p = (31-7k)/13
If: 2a+13 = 5a+1 Then: a = 4
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
7+6
Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
