Q. Solve for x and write your answer in simplest form.10x−(x+1)=−3(−x−45)−43Answer: x=
Distribute terms in parentheses: First, let's distribute the terms inside the parentheses on both sides of the equation.On the left side, distribute the 10 to x and −1 to get 10x−(x+1).On the right side, distribute −3 to both −x and −45 to get −3(−x−45)−43.
Combine like terms: Now, simplify the left side by combining like terms. 10x−x−1 simplifies to 9x−1.
Simplify right side: Simplify the right side by multiplying −3 with each term inside the parentheses.−3(−x) gives us 3x, and −3(−45) gives us 415. So, the right side becomes 3x+415−43.
Combine fractions: Combine the fractions on the right side.415−43 simplifies to 412, which is 3.So, the right side is now 3x+3.
Simplify equation: Now we have a simplified equation: 9x−1=3x+3. Subtract 3x from both sides to get the x terms on one side. 9x−3x−1=3x−3x+3 simplifies to 6x−1=3.
Isolate x term: Add 1 to both sides to isolate the term with x.6x−1+1=3+1 simplifies to 6x=4.
Add 1 to both sides: Finally, divide both sides by 6 to solve for x.66x=64 simplifies to x=32.
