How many real solutions does the equation y=12x-9x+4 have?
jek_recluse [69]

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

<span> 3.1 </span>    Solve  <span> <span>y-12x2+9x-4</span> </span> = 0 

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