this a tricky one
hei my name is Jeff i turned 21 about a week ago, for mi birthday I got a potato flying aroun mi room
whoops small typo (1/5)*(15+5a) = ?
@yolomcswagginsggg no random comments on my question pplease
nope, not quite (1/5)*15 = ?
nope, not quite... hint: (1/5)*15 = 15/5 = ?
3? are we dividing 15/5?
multiplying by 1/5 is the same as dividibg by 5
now (1/5)*5a = ?
srry my laptop cut off
1a? im confused
yes, a (we usually write 1a as a)
now we have a + 5 = a + 3 notice what happens when subtract away a from each side
yea just confused
subtract a from each side
it would be 1?
a + 5 - a = ?
4? a would be 1?
hint: a - a = ?
are you sure? hint: 1 - 1 = 0 a - a = ?
ok, so a-a=0
good, so what is a + 5 - a ?
good. a + 3 - a = ?
good. so now we have 5 = 3 notice something unusual about this statement? when we solve an equation and get a false statement like this, there is no solution
in other words, there is no value of a that can make 5 equal 3
i see. thank you!
