Evaluate Expressions for x = 2

Evaluate the following expressions for x = 2.

Evaluate the following expression for x = 2.

Answer:

-9.2(4 - 2) = -18.4

-36.8 + 9.2*2 = -18.4

Explanation:

Given:

-9.2(4 - x)

-36.8 + 9.2x

Required:

Evaluate when x = 2

-9.2(4 - x)

Substitute 2 for x

-9.2(4 - x) = -9.2(4 - 2)

Evaluate the expression in the bracket

-9.2(4 - x) = -9.2(2)

Remove the bracket

-9.2(4 - x) = -9.2*2

-9.2(4 - x) = -18.4

-36.8 + 9.2x

Substitute 2 for x

-36.8 + 9.2x = -36.8 + 9.2 * 2

-36.8 + 9.2x = -36.8 + 18.4

-36.8 + 9.2x = -18.4
