To solve the equation \( 21(2-x)+12 x=44 \), we start by simplifying it: 1. Distribute \( 21 \) in the first term: \[ 42 - 21x + 12x = 44 \] 2. Now combine like terms: \[ 42 - 21x + 12x = 44 \] \[ 42 - 9x = 44 \] 3. Next, isolate the term with \( x \): \[ -9x = 44 - 42 \] \[ -9x = 2 \] 4. Finally, divide by -9 to solve for \( x \): \[ x = -\frac{2}{9} \] The solution to the equation \( 21(2-x)+12 x=44 \) is \( x = -\frac{2}{9} \). In case you're wondering, this type of equation is common in algebra, often found in mathematics textbooks and courses that cover linear equations. Solving it helps to improve your problem-solving skills as you get familiar with combining like terms and isolating variables. If this kind of problem excites you, there're plenty of resources and interactive platforms online where you can practice similar equations.
