Question

If (2 x - 1) + (x - 1) = x + 2 so x = _________.
(a) -1 (b) 2 (c) -2 (d) 1​

Answer 1

Answer:

b. 2

Step-by-step explanation:

2x-1+x-1 = x+2

=> 3x-2 = x+2

=> 2x = 4

=> x=2

Answer 2

answer - x = 2 ( b)

→ (2x - 1) + x - 1 = x + 2 (remove unnecessary parentheses)

→ (2x - 1) - 1 = 2 ( cancelling equal terms such as in this question +x and x because they will have no impact in the final answer and would come out as 0)

→2x - 1 - 1 = 2 (remove unnecessary parentheses)

→ 2x - (1+1) = 2 { show this process if necessary}

→ 2x - 2 = 2

→ 2x = 2+2 (moving constant to right side)

→ 2x = 4

→ 2x ÷ 2 = 4 ÷ 2 ( dividing both sides with 2 )

→x = 2
