You can put this solution on YOUR website!
2(x-3) - 3(x + 5) = 3(x-2) - 7
\n" ); document.write( ":
\n" ); document.write( "Mult what's inside the brackets, remember to change the sign inside the brackets if there is a negative outside the brackets
\n" ); document.write( ":
\n" ); document.write( "2x - 6 - 3x - 15 = 3x - 6 - 7
\n" ); document.write( ":
\n" ); document.write( "generally we perform operations to get the unknown (x) on the left and the numerical values on the right. (Altho it's Ok to reverse that if you like)
\n" ); document.write( ":
\n" ); document.write( "2x - 3x - 3x = -6 -7 + 6 + 15
\n" ); document.write( ":
\n" ); document.write( " -4x = +8
\n" ); document.write( ":
\n" ); document.write( "x = +8/-4
\n" ); document.write( ":
\n" ); document.write( "x = -2
\n" ); document.write( ":
\n" ); document.write( "You can prove your solution by substituting -2 for x in the original equation and see if equality reigns
\n" ); document.write( ":
\n" ); document.write( "2(x-3) - 3(x + 5) = 3(x-2) - 7
\n" ); document.write( ":
\n" ); document.write( "2(-2 -3) - 3(-2 +5) = 3(-2-2) - 7
\n" ); document.write( ":
\n" ); document.write( "2(-5) - 3(+3) = 3(-4) - 7; did the math inside the brackets
\n" ); document.write( ":
\n" ); document.write( "-10 - 9 = - 12 - 7
\n" ); document.write( ":
\n" ); document.write( "-19 = -19 proves that x = -2
\n" ); document.write( "
