To eliminate the fraction, we can multiply both sides of the equation by 100:76x=38×100Calculating the right side:76x=3800 Step 5: Solve for xNow, divide both sides by 76 to find x:x=380076Calculating this gives:x=50 Step 6: Verify the solutionTo verify, we substitute x=50 back ...
After studying this section, you will be able to:1. Solve equations of the form x+b=c using the addition principle.2. Using the Addition PrincipleWhen we use the equals sign (=), we indicate that two expressions are equal in value. This is called an equation. For example, x+5=23 ...

x = In.x is not quite in the form = f(x) . However. we can rearrange the equation to give 一 (Which is now in the form= f(x) ) ∴y=1/2(lnx)^2+c L.e, we ecognised the ntegral as h()[h()d=h(x)]" + e where h(x) = In That is, we have a general solution...
Solve the equation, f(x) = g(x). For what value of x does f(x) = g(x)? Solving Linear Equations Whenever we have to linear equations, we can graph them in the Cartesian coordinate system which is a system of two perpendicular axes. In order to find the solution ...
