Answer:

-9.2(4 - x) = -18.4

-36.8 + 9.2x =-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 bracket

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

Remove 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
