Solve the equation for x. 20(2x − 8) = 440 a) 2 b) 5 c) 9 d) 15

D) 15

Step-by-step explanation:

To solve for the equation 20(2x - 8) = 440, we will need to work backwords to isolate the variable, x.

First, simplify both sides of the equation:

20(2x − 8) = 440

(20)(2x) + (20)(−8) = 440

40x + (−160) = 440

40x − 160 = 440

Second, add 160 to both sides.:

40x - 160 = 440

40x − 160 + 160 = 440 + 160

40x = 600

Third, divide both sides by 40:

40x  = 600

40x/40 = 600/40

x = 15
