Solving Linear Equations in One Variable - Algebra 2

Solve for a

 $8a\ -\ 12\ =\ 3a\ +\ 7$  

• a = 3.8

• a = 95

• a = 19

• a = 3.4

Solve for c

 $4c\ -\ 2\left(c+6\right)\ =\ 3\left(2c+7\right)\ +\ 5$  

• c = -9.5

• c = -38

• c = 4

• c = -1/2

Solve for k

 $k\left(k+3\right)\ +5=k^2+7k\ -10$  

•  $3\ \frac{3}{4}$  

•  $3\ \frac{1}{4}$  

•  $3\ \frac{1}{2}$  

Solve for b

 $\frac{b\ +7}{2b}=\frac{4}{5}$  

•  $11\ \frac{2}{3}$  

• 35

•  $11\ \frac{3}{4}$  

•  $10\ \frac{2}{3}$  

Solve for X

 $4\ -\ \left(3-x\right)\ =\ x\ +\ 5$  

• No solution

• X = 6

• X = 3

• Cannot be solved

Solve for X

 $2\left(x+1\right)\ -\ \left(x-2\right)\ =\ x\ +4$  

• Any value of X works

• X = 4

• No Solution

• X = 3

• It is an identity

Solve for w

 $P\ =\ 2w\ +\ 2l$  

•  $\frac{P-2l}{2}$  

•  $P\ -\ l$  

• w = 2

•  $\frac{P}{2}-l$

Solve for X

 $ax+c\ =\ bx\ +10$  

•  $\frac{10-c}{a-b}$  , a  $\ne$  b

•  $a\ -b$  

•  $\frac{a}{10-c}$  

•  $\frac{c}{a-b}\ ,\ a\ \ne b$  

 $7\left(a-3\right)-5\left(2a-4\right)=5$
