Question

Given that

P
=
7
x
+
20
−
2
y
.
Find
P
when:
x
=
2
and
y
=
6

Answer 1

• P = 22

Explanation:

We know that:

• P = 7x + 20 − 2y
• x = 2
• y = 6

Work:

• P = 7x + 20 − 2y

Substituting the given values

• P = 7(2) + 20 − 2(6)

Solving

• => P = 14 + 20 - 12
• => P = 22

Hence, the value of P is 22.
