Question

Solve x2 - 4 = 77.
What’s is the answers

Answer 1

Do you mean 2x - 3 = 77? if so here's your answer bud,

Explanation:

2x - 3 = 77

we can send 3 to rhs from lhs (from left hand side to right hand side)

when we send a number to another side it changes it's sign then it will be...

2x = 77+3

so, 2x = 100

now we can send 2 to rhs from lhs and then it will change it's sign from multiplication to division

so, x =
`(100)/(2)`

the answer is 50 :D
