7x +5 = 3x - 11
what is the answer to this and how to do i solve it

Let me answer those two questions in the reverse order.

1).  How it can be solved:

                                       7x + 5  =  3x - 11
Subtract  3x
from each side:            4x + 5  =        - 11

Subtract  5
from each side:            4x         =        - 16

Divide each side
by  4 :                              x          =        - 4

2).  The answer is  x = - 4 .
-4 is called the 'solution' to the equation, because that's the number
that 'X' MUST be.  If it's any other number, then the equation is not
a true statement.

pretty sure its b

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
