Hello There:\r \n" ); document.write( "\n" ); document.write( "Since there is only one equation, this is not a system of equations. I've moved your post to the linear equation section.\r \n" ); document.write( "\n" ); document.write( "n - 4*(1 + 5*n) = -2\r \n" ); document.write( "\n" ); document.write( "The goal is to isolate n on one side of the equals sign. Since the variable appears inside parentheses, we need to get rid of them. Use the distributive property to do this. Multiply both the 1 and the 5*n by -4.\r \n" ); document.write( "\n" ); document.write( "n - 4 - 20*n = -2\r \n" ); document.write( "\n" ); document.write( "Now we can combine the two terms containing the variable.\r \n" ); document.write( "\n" ); document.write( "-19*n - 4 = - 2\r \n" ); document.write( "\n" ); document.write( "Add 4 to both sides to isolate the term -19*n.\r \n" ); document.write( "\n" ); document.write( "-19*n = 2\r \n" ); document.write( "\n" ); document.write( "The last step is to divide both sides by -19. This solves the equation for n.\r \n" ); document.write( "\n" ); document.write( "n = -2/19\r \n" ); document.write( "\n" ); document.write( "~ Mark \n" ); document.write( " \n" ); document.write( " |
