Question

4 - (x - 1) = 7 - 2x​

Answer 1

Step-by-step explanation:

4-(x-1) =7-2x

-4x+4=7-2x

-4x+2x = 7-4

-2x=3

X=3/-2

Answer 2

Answer:

Step-by-step explanation:

4 - (x - 1) = 7 - 2x

⇒ 4 - x - 1 = 7 - 2x

⇒ 3 - x = 7 - 2x

⇒ - x + 2x = 7 - 3

⇒ x = 4

Justification:

Substituting the value of x in 4 - (x - 1) = 7 - 2x​, We get:

4 - (4 - 1) = 7 - 2(4)

⇒ -1 = -1
