Question

Evaluate the expression 2(2-y)-x When y = 8 and x = -3, what is the value of the expression?​

Answer 1

Your answer will be (-9)

This is how I got my answer-

2(2-y)-x

2(2-8)-(-3)

2 - 8= (-6)

2 × (-6) = (-12)

(-12) - (-3) = (-9)

Answer 2

-9

Explanation:

y = 8

x = -3

• 2(2-y)-x = ⇒ replace x and y with their values
• 2(2 - 8) - (-3) = ⇒ solve parenthesis
• 2(-6) + 3 = ⇒ multiply
• -12 + 3= ⇒ add
• - 9 ⇒ answer
