Solve.

 $6a\ +\ 5a\ =\ -11$  

•  $a\ =\ 0$  

•  $a\ =\ 1$  

•  $a\ =\ -1$  

• None of these

 $4x\ +\ 6\ +\ 3\ =\ 17$  

•  $x\ =\ 6.5$  

•  $x\ =\ -6.5$  

•  $x\ =\ -2$  

•  $x\ =2$  

 $24\ =\ 3\left(3x\ -7\right)$ 

•  $x\ =\ -9$  

•  $x\ =\ 5$  

•  $x\ =3$  

•  $x\ =\ 7$  

 $r\ +\ 11\ +\ 8r\ =\ 29$  

•  $r\ =0$  

•  $r\ =\ 1$  

•  $r\ =\ 2$  

•  $r\ =\ 3$  

 $50\ =-5\left(6n\ +\ 8\right)$  

•  $n\ =9$  

•  $n\ =\ -3$  

•  $n\ =-10$  

•  $n\ =\ -20$  

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Solve for n:
2m - n = 8

• n = 2m - 8
• n = -2m - 8
• n = 2m + 8
• n = -2m + 8

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

Solve the equation for w.  
^{x = w / a}

• w = a / x
• w = x / a
• w = ax
• x = wa

A-B = C
(solve for A) 

• A = C - B
• A = C + B
• A - C = B
• B = A - C
