Algebra.Com's Answer #418938 by IWork4Dessert(60)![]() ![]() You can put this solution on YOUR website! -5x+12=6 \n" ); document.write( "Your goal in any equation with a variable in it--otherwise known as a letter--is to get that letter by itself. \n" ); document.write( "Before we get the x away from the -5, which is stuck to it right now, we need to get rid of the 12 that's hanging around on that side of the equation. \n" ); document.write( "To do this, subtract 12 from both sides(since it's +12, just make it opposite to cancel out the signs; - and + cancel each other out). But you have to do the same thing on both sides of the equation, so you also subtract 12 from the 6, which equals -6. \n" ); document.write( "-5x=-6 \n" ); document.write( "Now, the -5 is still chillin like a villain around the x. Since whenever two numbers(or a variable and a number) are right next to each other, it means you're multiplying--for example, (3)(4)=12--you'll have to divide both sides by -5 to get rid of it, similarly to how you subtracted the 12. \n" ); document.write( "x=6/5 \n" ); document.write( "The answer is positive because when two -'s are together, they cancel out to make a +. Always remember that - & - = +, but + & - = -. \n" ); document.write( "Let me know if you need more help! \n" ); document.write( " |
