distribute parenthesis by 6
OpenStudy (anonymous):
Ok (42m - 36)
Nnesha (nnesha):
yes right now you can remove that parenthesis
OpenStudy (anonymous):
Ok
Nnesha (nnesha):
\[\huge\rm 42m -36 + 6 = 306\]
combine like terms on left side

Ok so you plus 6 to the 36 right?
Nnesha (nnesha):
YES but 36 is negative
so -36 + 6 = ?
OpenStudy (anonymous):
So..... 42m - -30 now?
Nnesha (nnesha):
-36 + 6 = -30 so there should be one negative sign
\[\huge\rm 42m - 30 = 306\]
now solve for m
OpenStudy (anonymous):
Ok 42m - 30 = 306
-42 -42 =
254

Nnesha (nnesha):
nope 42 is multiplying with m
so first step to move -30 to the right side
so add 30 both side first
then divide by 42
OpenStudy (anonymous):
Ohhhhh
OpenStudy (anonymous):
So it will be 336
Nnesha (nnesha):
final answer ??
OpenStudy (anonymous):
M= 336

Nnesha (nnesha):
nope when yo uadd 30 both side yo uget 336 but left side u still have 4m\[\huge\rm 4m = 336\]
Nnesha (nnesha):
now divide both side by 4
Nnesha (nnesha):
what you get ?
OpenStudy (anonymous):
M=84
Nnesha (nnesha):
336/4 =?

Nnesha (nnesha):
|dw:1424417524542:dw|
that's what we got after combining like terms right
