We start by subtracting 49 from both sides to isolate the variable x: $$7x - 49 + 49 = 21 + 49 \Rightarrow 7x = 70.$$ Dividing both sides by 7 gives us $$x = 10.$$ Therefore, choice C, $x=10$, is the correct answer.

Solve the Following Equation 7x−49=217 x - 49 = 217x−49=21 A) x=4x = 4x=4

Solve the Following Equation $7 x - 49 = 21$ A) $x = 4$
