Question

Literal Equations:

 

Solve for X. 3x+1/4y=z

Solve for x1.  m=y2-y1/x2-x1

Answer 1

(1).  Assuming that the equation is (3x+1)/4y = z

 

                   3x + 1 = 4yz

 

                          3x = 4yz - 1

 

                            x = (4yz - 1)/3

--------------------------------------------------------------------------

(2).  Assuming that the equation is (y₂ - y₁)/(x₂ - x₁) = m

 

                 m(x₂ - x₁) = y₂ - y₁

 

                 mx₂ - mx_{1 =} y₂ - y₁

 

                          -mx₁ = y₂ - y₁ - mx₂

 

                              x₁ = (mx₂ + y₁ - y₂)/m

 

                 

Answer 2

You need to use parenthesis to clarify groupings/order of operations before anyone can help you.
