Q. 3x3x monus 77 equal 66
  1. Write Equation: First, let's write down the equation correctly, it's 3x−7=63x - 7 = 6.
  2. Isolate Variable: Now, we need to isolate the variable xx, so let's add 77 to both sides of the equation to get rid of the −7-7.3x−7+7=6+73x - 7 + 7 = 6 + 7
  3. Add and Solve: After adding, we get 3x=133x = 13.
  4. Divide and Solve: Next, we divide both sides by 33 to solve for xx.3x3=133\frac{3x}{3} = \frac{13}{3}
  5. Final Result: So, xx equals 44 and a third, or 4.333…4.333\ldots
