Explanation: In order to solve for x, we must get x by itself on one side of the equation. The equation is: -8-5n=64+3n 5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation. -8-5n+5n=64+3n+5n -8=64+3n+5n -8=64+8n 64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation. -8-64=64-64+8n -8-64=8n -72=8n n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8. -72/8=8n/8 -72/8=n -9=n
