Answer 2

solving
2x - 5 = 27
add 5 to both sides
2x - 5 + 5 = 27 + 5
2x = 32
divide both sides by 2
x = ?

Answer 3

can you finish it off/

Answer 4

idk whats the answer

Answer 5

2x / 2 = x
32 / 2 = ?

Answer 6

s = 32/2 = ?

Answer 7

16 okay but the answer choices are up there

Answer 8

yea - now what you do is find which choice fits x = 16
for example try the first one:-
3 + 5x = 58
plug in x = 16
3 + 5*16
= 3 + 80
= 83 NOT 58 so it cant be choice 1

Answer 9

ok......

Answer 10

now try the others

Answer 11

for b you want to see if 3*16 - 2 = 31
3*16 - 2 = ?
