Question

If p=-1 q=-2 . Find the value 10-3p-4+6q

Answer 1

Answer

25

Step-by-step explanation:

= 10-(3*-1 )+(6*-2)

= 10-(-3)+(-12)

= 10-(-15)

=25

Answer 2

Answer:

As men5ioned in the question they tell you that

$p = - 1 \\ q = - 2$

First we have to understand what 3p means.

When a variable and a number are written together without a operation between them it means we have to multiply tjem.

For ex- 4b

In this we multiple 4 by b.

Now lets start solving the equation.

Lets rewrite it once for better understanding.

$10 - 3p - 4 + 6q$

Now as I told when there is no operation between variable and digit it means we have to multiply. So as BODMAS says to multiply first we will do that.

$10 - (3 \times p) - 4 + (6 \times q)$

we can pit it in brackets to prevent any confusions.

So lets solve 3p first. As aldready mentuoned p = -1, We multiply by -1.

$3 \times p \\ = 3 \times ( - 1) \\ = - 3$

Now lets solve 6q. we already know that q equals to -2, So we multiple 6 by -2.

$6 \times q \\ = 6 \times ( - 2 ) \\ = - 12$

We have solved lets write the equation again with solved algebra.

$10 - ( - 3) - 4 + ( - 12)$

We will remove all brackets first remember -- =+ .

$10 + 3 - 4 - 12$

Bodmas says addition first.

$13 - 4 - 12$

start subtracting from left.

$9 - 12$

SOLVE! :)

$- 3$

Done! Hope it helps you.
