Question

5 + 2(x - 1) = x + 4(x - 3)​

Answer 1

This will be the answer.

Answer 2

Answer:

$\:$

$\rightarrow5 + 2(x - 1) = x + 4(x - 3)$

$\:$

multiply 4 × (x-3)

$\:$

$\rightarrow5 + 2(x - 1) = x + 4x - 12$

$\:$

Then, add 5 + 2

$\:$

$\rightarrow7x - 7 = x + 4x - 12$

$\:$

Add 4x - x

$\:$

$\rightarrow7x - 7 = 5x - 12$

$\:$

Collect the like terms.

-7 will go to right hand side and become +7 and +5x will go to left hand side then it will become -5x

$\:$

$\rightarrow7x - 5x = - 12 + 7$

$\:$

Now subtract 7x - 5x and work out -12 - 7

$\:$

$\rightarrow2x = - 5$

$\:$

Now bring 2 to the right hand side and will become ÷2

$\:$

$\rightarrow x = \dfrac{ - 5}{2}$

$\:$

now cancel -5/2

$\:$

$\rightarrow x = \dfrac{ \cancel{ - 5}}{ \cancel2}$

$\:$

$\rightarrow x = - 2.5$

$\:$

$\:$

•°• Therefore, value of x = -2.5
