Question

11z-3-7z=9

Answer 1

mmm what is (11-7)z =

Answer 2

4

Answer 3

yes...
11z-3-7z=9 means
(11-7)z-3 = 9
which gives
4z-3 = 9;

Now do you want to solve for z?

Answer 4

thats where i get stuck

Answer 5

3 to get 9?

Answer 6

sorry my message didnt sent completely

Answer 7

do i find a number to multiply

Answer 8

do i find a number to multiply 4 with and then subtract it from 3 to get 9?

Answer 9

well let us get moving fromwher you got stuck.....
equality has a property that if you add or subtract or multiply or divide by same number on both side of equality the result won't be altered....
so.... that is
a+b =x
is same as
a+b+c= x+c
a+b-c= x-c
(a+b)*c= x*c
(a+b)/c = x/c

Answer 10

yes you can find a number which satisfies your rlation by using above property of equality

Answer 11

any idea how?

Answer 12

4 times 3 =12-3=9?

Answer 13

How you got 4 times 3??

Answer 14

4z= 4(3)=12
or am i wrong

Answer 15

yes... the method you followed is a round about way...but there is an alternate simple 100% guarntry way using the above property wanna learn it?

Answer 16

yes please

Answer 17

:)
so aftr simplification of 11z-3-7z=9
we got
4z-3 = 9
now add 3 to both sides of equality ( the result will not change because of the property
a+b =x is same as a+b+c= x+c)
what you get

Answer 18

12

Answer 19

please type full equation

Answer 20

means both RHS and LHS

Answer 21

rhs? lhs?

Answer 22

means RHS = Right Hand Side
LHS = Left Hand Side
of equation

Answer 23

im so lost im very sorry

Answer 24

in this equation
a+b =x
a+b is LHS
x is RHS
