Question

7+6x-(-5x+(-4x)), если X=2

Answer 1

7+6х+5x+4x=7+15x

Если х=2, то 7+30=37

Ответ: 37

Answer 2

Ответ:

7x + 6x - (-5x +(-4x))

При x = 2

= 14 + 12 - ( - 18) = 26 + 18 = 44

Answer 3

To evaluate the expression 7 + 6x - (-5x + (-4x)) when x = 2, you need to substitute the value of x into the expression and perform the arithmetic operations.

Step 1: Substitute x = 2 into the expression: 7 + 6(2) - (-5(2) + (-4(2)))

Step 2: Simplify the expression using the order of operations (PEMDAS/BODMAS):

1. First, solve the expression inside the innermost parentheses: 7 + 6(2) - (-5 * 2 + (-4 * 2)) 7 + 12 - (-10 + (-8))

2. Now, solve the expression inside the second set of parentheses: 7 + 12 - (-10 + (-8)) 7 + 12 - (-10 - 8)

3. Next, perform the subtraction inside the parentheses: 7 + 12 - (-10 - 8) 7 + 12 - (-18)

4. Finally, perform the subtraction outside the parentheses: 7 + 12 + 18

Step 3: Complete the final addition: 7 + 12 + 18 = 37

So, the value of the expression 7 + 6x - (-5x + (-4x)) when x = 2 is 37.
