Question

How many real solutions does the equation y=12x-9x+4 have?

Answer 1

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     y-(12*x^2-9*x+4)=0 

Step by step solution :Step  1  :Equation at the end of step  1  : y - (((22•3x2) - 9x) + 4) = 0 Step  2  :Equation at the end of step  2  : y - 12x2 + 9x - 4 = 0 Step  3  :Solving a Single Variable Equation :

 3.1     Solve   y-12x2+9x-4  = 0 

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
