➤ [ Step One ] Divide Both Sides By 3

$\bold{\frac{3\left(x+6\right)}{3}=\frac{39}{3}}$

➤ [ Step Two ] Simplify

$\bold{x+6=13}$

➤ [ Step Three ] Subtract 6 From Both Sides

$\bold{x+6-6=13-6}$

7x+2y=4 y=x+1 Solve the system of equations. (1/3,4/3) (2/9,11,9) no solution

Lunna [17]

Answer: SECOND OPTION

Step-by-step explanation:

You can solve the system of equations by the method of substitution:

- You must susbtitute the second equation into the first equation and solve or x:

$7x+2(x+1)=4\\7x+2x+2=4\\9x=4-2\\9x=2\\x=\frac{2}{9}$

- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:

$y=\frac{2}{9}+1\\\\y=\frac{2+9}{9}\\\\y=\frac{11}{9}$

Therefore, you obtain:

( $\frac{2}{9},\frac{11}{9}$ )

Bad White [126]

B) (1, 5) is your best answer

B (0,6) creates the top of the kite
D (0,2) creates the bottom
A (-1,5) creates the left side of the kite
D (1,5) creates the right side (only the x is flipped, because has congruent sides of both the top, and both the bottom.

hope this helps
