Question

Make a the subject of the formula:
10a+1= -46 – 5

Answer 1

`a = ( - 46 - 5 - 1)/(10)`

Explanation:

`10a + 1 = - 46 - 5 \\ 10a = - 46 - 5 - 1 \\ (10a)/(10) = ( - 46 - 5 - 1)/(10)`

`a = - ( - 46 - 5 - 1)/(10)`

It you were asked to solve for a ur would be;

`a = - ( 52)/(10) \\ or \: \\ a = - ( 26)/(5)`

Answer 2

The answer is

a = (-46 – 5 – 1) ÷ 10

Explanation:

Given;

• 10a + 1 = -46 – 5

So,

10a + 1 = -46 – 5

Now, subtract 1 from both side we get,

10a + 1 – 1 = -46 – 5 – 1

10a = -46 – 5 – 1

Now, divide by 10 from both side we get,

10a/10 = -46 – 5 – 1/10

a = (-46 – 5 – 1) ÷ 10

Thus, a is the subject of the given formula.

If you want to find the value of a then,

a = (-46 – 5 – 1) ÷ 10

a = (-52)/10

a = -5.2

Hence, The value of a is (-5.2).
