Hey, \n" ); document.write( "So for this one we need to write what we know in numbers and variables: \n" ); document.write( "2x - 7 = 19 \n" ); document.write( "To solve this equation, we need to isolate the x. So first we add 7 to both sides to get rid of it on the left side: \n" ); document.write( "2x - 7 + 7 = 19 + 7 => 2x = 26 \n" ); document.write( "Now we divide both sides by 2 to get rid of the 2 on the left side: \n" ); document.write( "2x/2 = 26/2 => x = 13 \n" ); document.write( "Now we need to solve 4x. Since x = 13, we substitute 13 for x in the equation: \n" ); document.write( "4 (13) = 52 \n" ); document.write( "I hope this helps! \n" ); document.write( " |
