-4x + 15 > 59 bit stuck on this on this stuff please help

ganeshie8 (ganeshie8):

start by subtracting 15 both sides

OpenStudy (anonymous):

-19 and 44

OpenStudy (anonymous):

?

ganeshie8 (ganeshie8):

hey no, you cannot subtract apples and coconuts

ganeshie8 (ganeshie8):

-4x + 15 > 59 subtract 15 both sides -4x + 15 > 59 -15 -15 -4x > 44 divide -4 both sides x < -11

OpenStudy (anonymous):

OHHHHHHH

ganeshie8 (ganeshie8):

thats the entire solution, see if it helps

OpenStudy (anonymous):

one more little question how do you know what to subtract on both sides

ganeshie8 (ganeshie8):

thats a very good question :)

ganeshie8 (ganeshie8):

-4x + 15 > 59

ganeshie8 (ganeshie8):

looking at that thing, our goal is to ISOLATE x

ganeshie8 (ganeshie8):

since +15 is there on both sides, to isolate x, i thought i would subtract 15 both sides, so that 15 goes away on left side

ganeshie8 (ganeshie8):

-4x + 15 > 59 -15 -15 -4x > 44

ganeshie8 (ganeshie8):

see, half the work is done already, just by subtracting 15 both sides see how the left side looks lean and thin :)

OpenStudy (anonymous):

ooohhh makes sense

OpenStudy (anonymous):
