anonymous · Answer

example          3x + 2x =  10
                               5x = 10          x = 10/5        x = 2

anonymous · Answer

Oh I see you just combined 3x and 2x to make 5 and then divided 10 by 5 which gives you 2. But im just confused by the part where you have to replace the answer in 2x-1

anonymous · Answer

Because apparently the answer is 3 but i dont get how its is since i keep getting 6

anonymous · Answer

for eg you need     5x - 3      and you got x = 5
                           then you do       5 ( 5 ) - 3
                                                     25 - 3    =  22

finally  you say    5x - 3   = 22

anonymous · Answer

come try it

anonymous · Answer

then 5x - 3=22
            +3  +3
       5x= 26
        5 = 5         x=5.2

am i right??
