Solve for x.

\[ ax + bx = 21 \]

ax + bx = 21
factor out x
x(a + b) = 21 x = 21/(a+b)

ax+bx =21 on factorising x, we get x( a+b) =21 x = 21/a+b

To solve a x + b x = 21 , factor out x to get x ( a + b ) = 21 . Then, isolate x by dividing both sides by a + b , resulting in x = a + b 21 ​ . Ensure that a + b is not zero to avoid division by zero.
