Question

Malik solved the equation 2x – 3(2x – 9) = 4 – (3x – 11) using the steps shown below.

Answer 1

2x -6x + 27= 4-3x +11
2x-6x+3x= 4+11-27
-1x= -12
x=12

Answer 2

Answer:

$x=12$

Step-by-step explanation:

Given Equations are -

$2x-3(2x-9)=4-(3x-11)$

It is required to solve the given equations in four steps only.

Step 1 - solve the brackets first

$2x-3(2x-9)=4-(3x-11)\\2x-6x+27=4-3x+11$

step 2 - put all variable values on one side and constant values on other side

$2x-6x+27=4-3x+11\\2x-6x+3x=4+11-27$

step 3- Do the addition and subtraction on LHS and RHS of the equation

$2x-6x+3x=4+11-27\\-x=-12$

step 4- removing the minus sign on both sides

$-x=-12\\x=12$
