\qquad 5x+12+12+12-9=177\\ or\quad \quad 5x+27=177\\ or\quad \quad 5x=150\\ or\quad \quad \boxed { x=30 }

5x+12+12+12-9=177...... 177+9-(12+12+12)=150..... x=150/5=30;;;; x=30

as given that 5x + 12 + 12 + 12 - 9 = 177 5x = 177 + 9 - 36 5x = 150 x = 150/5 x = 30

$\begin{aligned} 5x + 12 + 12 + 12 - 9 & = 177\\ 5x + 27 & = 177\\ 5x & = 150\\ x & = \color{#69047E}{\boxed{30}} \end{aligned}$

$5x+12+12+12-9=177$

$5x+36-9 = 177$

$5x+27 =177$

$5x =150$

$x=\boxed{30}$

Step 1: Add 177 and 9. (186 is the sum)

Step 2: Compute the 12+12+12. ( 36 is the sum)

Step 3: Subtract 186 and 36. (150 is the difference)

Step 4: Divide 150 to 5. (30 is the overall answer)

We need to solve the equation.

$5x+12+12+12-9=177$

$5x+36-9=177$

$5x+27=177$

$5x=177-27$

$5x=150$

$x=30$

Thus, the answer is: $x=\boxed{30}$

I solved the problem backwards. first I did 177+9. Than I did 186-36 and got 150. Than I divided 150 by 5 and got 30.

5x+12+12+12-9=177 5x+27=177 5x=177-27 5x=150 x=150/5=30

(5.x)+(12+12+12)-9=177 (5 x)+(36~9)=177 5 x=177~27. 5*x=150. 150#5=30

This is just simple.

5.30+12+12+12-9=177

5x+12+12+12-9=177 5x+27=177 5x=177-27 5x=150 x=150/5=30

5x+12+12+12-19=177 just add the simillar so 12+12+12 =32 then u minus 19 = 27 .. so we have 5x+27=177 .. then next step u need to add unlike sign of 27 so it mean -27 seven so we can proceed now to our given we have 5x+27-27=177-27 so we cancel it so we and minus so we have 5x=150 so we need to divide both sie into 5 so we have 5x over 5 = 150 over 5 just Cancel the 5 and divide 150 into 5 so THEREFOE we have our FINAL answer x= 30 that's it :) i hope u understand mo explaination :D

5x + 12 + 12 + 12 - 9 = 177 5x+36 -9=177 5x+27=177 5x=177-27 x=150/5 x=30

5X==177-36+9 5X=150 X=30

5x+36-9=177 5x=150 x=30.

5x + 12 + 12 +12 - 9 = 177

5x + 27 = 177

5x = 177 - 27

x = 150 / 5

x = 50
