Question

What is the value of y when x = 2 is entered into y = 20x + (-2 • 5) ?

Answer 1

y=30

Explanation:

y= 20x+(-2x5) x=2

y=20(2)+(-2x5)

y=40+(-10)

y=30

Answer 2

y = 30

Explanation:

Given equation,

→ y = 20x + (-2 × 5)

The value of x is,

→ x = 2

Now the required value of y is,

→ y = 20x + (-2 × 5)

→ y = 20(2) + (-2 × 5)

→ y = 40 - 10

→ [ y = 30 ]

Hence, the value of y is 30.
