Answer 2

To simplify the given expression and find its value when a=3, b=2, and x=4, let's break it down step by step:

Step 1: Simplify the expression

(a+b)*5 + 9a + 3b + 6*(x+a) - 5a - 13*(a+b) - 7b + 4a + 30x - (5x+4x)

Step 2: Apply the order of operations (PEMDAS/BODMAS)

1. Start with the parentheses: (a+b)*5 + 9a + 3b + 6*(x+a) - 5a - 13*(a+b) - 7b + 4a + 30x - (5x+4x) (a+b)*5 + 9a + 3b + 6*(x+a) - 5a - 13*(a+b) - 7b + 4a + 30x - 9x

2. Next, perform the multiplications and divisions from left to right: (a+b)*5 + 9a + 3b + 6*(x+a) - 5a - 13*(a+b) - 7b + 4a + 30x - 9x 5(a+b) + 9a + 3b + 6(x+a) - 5a - 13(a+b) - 7b + 4a + 30x - 9x 5a + 5b + 9a + 3b + 6x + 6a - 5a - 13a - 13b - 7b + 4a + 30x - 9x

3. Combine like terms: 5a + 5b + 9a + 3b + 6x + 6a - 5a - 13a - 13b - 7b + 4a + 30x - 9x (5a + 9a + 6a - 5a - 13a + 4a) + (5b + 3b - 13b - 7b) + (6x + 30x - 9x) (19a - 9a) + (-8b) + (27x)

Step 3: Substitute the given values

Now, let's substitute a=3, b=2, and x=4 into the simplified expression: (19a - 9a) + (-8b) + (27x) (19*3 - 9*3) + (-8*2) + (27*4) (57 - 27) + (-16) + (108) 30 - 16 + 108 14 + 108 122

Therefore, when a=3, b=2, and x=4, the value of the expression is 122.

Please note that the explanation provided above is based on the given expression and the values of a, b, and x.
