x=8 in this equation.
Answer:
dunt know just doing it for the points
Step-by-step explanation:
Answer:
The answer is B, 5.
Step-by-step explanation:
3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).
12x+8 = 68
12x = 60
divide both sides by 12...
60/12 = 5.
Therefore x =5

Using these variables, we can set up equations.
3x + 5y = 42
9x + 7y = 72
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 3. Keep eq2.
9x + 15y = 126 eq1
9x + 7y = 72 eq2
Subtract eq2 from eq1 to eliminate the x terms.
8y = 54
y = 6.75
