Answer:

x = 3

Explanation:

  • 4x-11 = 7x-20 solve the following equation and verify your answer​

4x - 11 = 7x - 20

−3x + 9 = 0

x =
(-(9))/(-3)

x = 3

-----------------------------------

check

4 × 3 - 11 = 7 × 3 - 20 (remember PEMDAS)

12 - 11 = 21 - 20

1 = 1

same value the answer is good

Answer: x = 3

Explanation:

Our task is to solve the following equation:


\sf{4x-11=7x-20}

Rearrange:


\sf{7x-20=4x-11}

Add 20 to both sides:


\sf{7x=4x-11+20}


\sf{7x=4x+9}

Next, subtract 4x from both sides:


\sf{7x-4x=9}


\sf{3x=9}

Divide both sides by 3:


\sf{x=3}

Therefore, x = 3.
