Question

Q11. x = -1 is a solution of the
equation :
O
X-5 = 6
O 2x + 5 = 7
0 2(x - 2)+ 6 = 0
O 3x + 5 = 4​

Answer 1

Answer:

x = -1 is the solution of the equation :

2(x-2) + 6 = 0

Step-by-step explanation:

$Let's \: \: see, \: \: one \: \: by \: \: one \\ x - 5 = 6 \\ - 1 - 5 = 6 \\ \underline{ \underline{ - 6≠6}} \\ \\ 2x + 5 = 7 \\ 2( - 1) + 5 = 7 \\ - 2 + 5 = 7 \\ \underline{ \underline{3 ≠7}} \\ \\ 2(x - 2) + 6 = 0 \\ 2( - 1 - 2) + 6 = 0 \\ 2( - 3) + 6 = 0 \\ - 6 + 6 = 0 \\ \underline{ \underline{0 = 0}} \\ \\ 3x + 5 = 4 \\ 3( - 1) + 5 = 4 \\ - 3 + 5 = 4 \\ \underline{ \underline{2≠4}}$
