Am I right or wrong?

Question

y/4 + 2 = -1

y = 4

am I right...I think I am. unless it is 12

Answer 1

i believe you are wrong
the asnwer is -12
you are given...

y/4 + 2 = -1

first you need to get rid of the 4 so you multiply the whole thing by 4

(y/4 + 2 = -1) 4

so the result will be...

y + 8 = -4

***now you transpose the 8 to the other side, thus changing the sign...

y = - 4 - 8

now, since you are subtracting a positive from a negative you add them both...

y = -4 + -8

thus making your answer y = -12

***or you can do it this way,

from the equation, y + 8 = -4

you subtract 8 from both sides

y + 8 - 8 = - 4 - 8

simplifying it will give you,

y = - 12

Answer 2

y/4=-1-2(taking the 2 to rhs changes the sines)

y/4 = -3(on adding -1, -2)

y = -12 (on multiplying -3 and 4, coz when the 3 comes up to the RHS it becomes a multiply)

u were wrong.....u need some serious studying....and by the way what are u doing now?

Answer 3

Substitute your answers into the original equation, and see if it checks.

Does 4/4 + 2 = -1 ?
Does 12/4 + 2 = -1 ?

Sorry, no.

Does it seem reasonable that you need a negative value of y?

Answer 4

y/4+2=-1

Multiply by 4 all parts

y+8=-4
y+8-8=-4-8
y=-12

you were close except it should be -12

-12/4+2=-1
-3+2=-1 correct

Answer 5

it is either -12
or -6

it depends on (y/4) or y/(4+2)

Answer 6

its negative twelve (-12)

Answer 7

no
