Well, darling, a 2-step equation that equals 21 could be something like 2x + 5 = 21. First, you'd subtract 5 from both sides to get 2x = 16, then divide by 2 to find x = 8. Voila, you've got yourself a sassy solution!
1+3x=10

A two-step equation with a variable that equals 23 could be (2x + 5 = 23). To solve for (x), first subtract 5 from both sides to get (2x = 18), and then divide by 2 to find (x = 9). Thus, the solution satisfies the original equation.
An example of a two step equation that equals 2 is 4 + 2x = 2. In this equation, x = -1.
(1+3)/2
(n*0)+2
1 + 1 x 2.
1+3x=10
2x+2=12
21
it is 3x3 not that hard
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.
3 x - 7 = -21
It is a linear equation in two dimensional space. Such an equation defines a line in 2-d
