Answer:
The value of X is \bold{-\frac{8}{5}}−
5
8
.
To find the value of X for the given equation
\frac{X}{3}+1=\frac{7}{15}
3
X
+1=
15
7
The first step is take LCM
By taking LCM on the LHS
\frac{(X+3)}{3}=\frac{7}{15}
3
(X+3)
=
15
7
The equation will become after taking LCM
5X+15 = 7
15 is carried to the other side and its sign is changed to subtraction,
5X = 7-15
5X = -8
X=\frac {-8}{5}X=
5
−8
The answer will be in decimal form as it is not a balanced fraction.
