PLEASE HELP! Grade 9 Question: Find the root of each equation using pencil and paper. Check each root. a.) 1/2 (x+3)=5 b.) b-5/7 =3 c.) 6= 2/3 m-1 d.) -5= 3d+4/3
please don't tell me the answers, I just want to know how to do it, step by step, because I have a math exam tomorrow :)
a.) 1/2 (x+3)=5 multiply both sides by 2 x+3 = 10 now subtract 3 from both sides x= 7
you understand what i did??
hi sorry
in each equation you have one variable now its you job to separate that variable one one side and put all the constants on other side using maths
?
what happens to the fraction?
look at you question carefully a.) 1/2 (x+3)=5
you have to find the root for this equation. root means to find such value of x that satisfies this eqquation
oh...i see now
how would you do d?
a.) 1/2 (x+3)=5 now if you multiply both sides by 2 what you get ????
1(x+3)=10
10-3
x=7
exactly you got x= 7 which is the required root for this equation
thanks
to verify this that either your root is correct or incorrect just plug in this value in x in you question and see whether you get LHS = RHS or not if LHS = RHS then you calculated the correct root else wrong value
ok...
can you do the rest of questions or not???
yea, i think so, thanks
welcomeeeeeeee
