The table below shows two equations: Equation 1 |2x − 3| + 5 = 4 Equation 2 |5x + 3| − 10 = 3 Which statement is true about the solution to the two equations? Equation 1 and equation 2 have no solutions. Equation 1 has no solution and equation 2 has solutions x = 2, −3.2. The solutions to equation 1 are x = 1, 2 and equation 2 has no solution. The solutions to equation 1 are x = 1, 2 and equation 2 has solutions x = 2, −3.2.

no it will be positive the absolute function (this function-> | | ) always gives a positive output for example if u have this- |-3| then this will equal 3 so |-3|=3 and if u have this ->|3| then |3|=3 ok so far?

yes

we have this- |2x − 3| + 5 = 4 try to isolate the absolute term (that is the term in this-> | | )

x=2

how did u get this

2x-3+5=4 -5 -5 2x-3=-1 +3 +3 2x=4 divided by two equals x=2

1st of all -1+3=2 and u did 4 over there^ and |2x-3| is not the same as (2x-3) :)

ok ima tell :) so we have this- |2x − 3| + 5 = 4 subtract 5 from both sides we get this- |2x − 3| = -1 but we know that whenever anything is under this sign- | | the result is always positive but here we see that the result is negative so no solution ok?

oh okay

for the second part- |5x + 3| − 10 = 3 add 10 to both sides u get this- |5x + 3| = 13 now we know that |-13|=13 and |13|=13 so 5x+3=-13 or 5x+3=13 so x=-3.2 or x=2 :)
