Question

11. Find z in z/3+1= 17/15
a. 17/15
b.4.
c.2/5
d.3​

Answer 1

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.

Answer 2

Answer:

option (c) 2/5

Step-by-step explanation:

z/3+1 = 17/15

z/3= 17/15-1

z= 2/15•3

z= 2/5
