Answer 2

Answer:

The value of equation will be a $= 4$

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 3a-7=5

We have find the value of "a " in above equation

Here we will use the transposition method,

As we get,

$3a-7=5$

Adding both side by 7 we get

$3a-7+7=5+7$

Simplifying further we get,

$3a=12$

Divide both side by 3 we get,

$\frac{3a}{3} =\frac{12}{3} \\a=4$
