Answer 2

Answer:

The required value of  x $=\frac{11}{8}$ or, x$=1.375$

Step-by-step explanation:

As per the data in given equation

In above question it is given that

We have find the value of given expression

Given the data in question 8x+9=20

We have find the value of x in above equation

Here we will use the transposition method

As we get,

$8x+9=20$

Subtracting both side by 9 we get,

$8x+9-9=20-9$

Simplifying further we get,

$8x=11$

Divide both side by 8 we get,

$\frac{8x}{8} =\frac{11}{8} \\x=\frac{11}{8}$

or, x$= 1.375$

Hence required value of x will be $=\frac{11}{8}$ or, x$=1.375$
