Question

Simplify the following expression and find their values if x = 3, a = -3 : 5(x – a) + 2 (a – x)​

Answer 1

Answer:

If x = 3, a = -3 then 5(x – a) + 2 (a – x)​ = 18.

Step-by-step explanation:

if x = 3, a = -3

Then 5(x – a) + 2 (a – x)​

= 5[(3 - (-3)] + 2[(-3) - 3]

= 5[3+3] + 2[ -3 - 3]

=  5[6] + 2[ -6]

= 30 - 12

= 18
