d.-8

Answer 1

`\huge{HEY!!}`
_______________________________

▶We have to solve the expression 2x - 5 = 11

▶For solving this,

2x - 5 = 11

▶▶When we send 5 to another side, -5 will be changed to 5

2x = 11 + 5

2x = 16

▶▶When we send 2 on the another side, it will be divided

x =
`(16)/(2)`
x = 8

✔✔So, among these following options, "c" will be correct.

Answer 2

2x-5=11

2x=11+5

2x=16

x=16/2

x=8
