You would do it it by oppisites. 3+2+4=9 which equals C.
Solve the following equation for A : 2A/3 = 8 + 4A
3.5
12/3 = 4
You cannot solve one linear equation with two variables.
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
-3
You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.
-4
z=.3
Divide both sides by 100 n = 3

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.
