Answer 3

\[\bf \large 4.95+.35x=6.7\] Solve for x

Answer 4

one sec then

Answer 5

-4.96-6.7=11.66 right brb

Answer 6

uh, not quite, you want to subtract 4.95 from each side...

left side: 4.95+.35x
right side: 6.7

4.95+.35x - 4.95 = 6.7 - 4.95

keep going from here

Answer 7

-1.74

Answer 8

4.95+.35x - 4.95 = ?

Answer 9

9.9

Answer 10

not quite, remember that you can't combine variables and numbers...

4.95 - 4.95 = ?

Answer 11

0

Answer 12

right, so 4.95+.35x - 4.95 = ?

Answer 13

35x=0

Answer 14

4.95 - 4.95 = 0
4.95 + 0.35x - 4.95 = 0.35x, understood? we subtract 4.95 - 4.95 and leave 0.35x alone since it's got the letter x attached to it

Answer 15

now let's look at the right side: 6.7 - 4.95 = ?
