? how does x < 7 if there is -42 in the equation
OpenStudy (tkhunny):
Please apply algebra, rather than just guessing. 7x - 42 < 7 Add 42 7x - 42 + 42 < 7 + 42 7x - 0 < 49 7x < 49 Divide by 7 7x/7 < 49/7 (7/7)x < 7 (1)x < 7 x < 7 Really, it does not matter what you THINK the result should be or how you feel it should appear. Let's learn the mathematics and MAKE it what it is.
