Correct question:
Evaluate and simplify the expression when a = 3 and b = 2,
given expression = 3b-2(1 - b)a - 2
Answer:
3b-2(1 - b)a - 2 at the given values is 10.
Step-by-step explanation:
Given;
3b-2(1 - b)a - 2
The expression is simplified as;
3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2
= 3b - 2a + 2ab - 2
When a = 3 and b = 2; then, substitute these values in the simplified expression above;
3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2
= 6 - 6 + 12 - 2
= 10
Therefore, 3b-2(1 - b)a - 2 at the given values is 10.

Answer:
x = -5.975
Step-by-step explanation:
distribute first by multiplying 2/5 by 'x' and then by 9/10 to get:
2/5x - 18/50 = -2 3/4
next, change -2 3/4 into an improper fraction to get:
2/5x - 18/50 = -11/4
now add 18/50 to -18/50 and to -11/4 using a common denominator of 100
2/5x = -275/100 + 36/100
2/5x = -239/100
multiply each side by 5/2 to isolate 'x':
x = -239/100 · 5/2
x = -1195/200
now simplify:
x = -5.975
