Q. Which value of x satisfies the equation 31(x−21)=−21 ?12−2−1
Isolate variable x: First, we need to isolate the variable x in the equation 31(x−21)=−21. To do this, we can start by multiplying both sides of the equation by 3 to get rid of the fraction on the left side.31(x−21)×3=−21×3
Multiply by 3: After multiplying both sides by 3, we get:x−21=−23Now, we need to solve for x by adding 21 to both sides of the equation.
Add (1)/(2): Adding (1)/(2) to both sides gives us:x−21+21=−23+21This simplifies to:x=−23+21
Combine fractions: Now we combine the fractions on the right side of the equation:x=2−2+21x=2−1
Final value of x: We have found the value of x that satisfies the equation:x=−21However, this value is not listed in the options provided. We need to check our calculations to see if there was an error.
