Linear Equations in One Variable Page 33"
Answered by admin @
Equations with linear expressions in one variable only are
known as linear equations in one variable.
An algebraic equation is an equality involving variables. It
has an equality sign(=). The expression on the left of the equality sign is the
Left Hand Side (LHS). The expression on the right of the equality sign is the
Right Hand Side (RHS).
In an equation the values of the expressions on the LHS and
RHS are equal.
Transposition:
Any term of a equation may be taken from one side to other
with the change in its sign, this does not affect the equality of the statement
. This process is called transposition.
=========================================================
Solution:
X+7 -8x/3 = 17/6 – 5x/2
X+7 -8x/3 +5x/2= 17/6
[ Transposing 5x/2 to L.H.S]
LCM of the denominators 2, 3 is 6.
[6(x+7)- 2(8x)+3(5x)]/6=17/6
6x+42-16x+15x=6× (17/6)
6x
-16x+15x+42= 17
-10x+15x=17-42
[Transposing
42 to R.H.S]
5x=
-25
x= -25/5
X= -5

Hope this will help you.....
