As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.

-4x=10 and -7x is 65? -4x=10 therefore 4x is -10, x = -2.5 -7x = 65, 7x = -65, x = -9.26

In the expression (4x^3 - 7x^2 \times x^3), the like terms are those that have the same variable raised to the same power. Here, (4x^3) and (-7x^2 \times x^3) can be simplified to (-7x^5). Thus, the like term in this case is (4x^3) and (-7x^5), but they are not like terms since they are raised to different powers. Therefore, there are no like terms in the expression.
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
7x = 4x - 93x = -9x = -3
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
To simplify the expression (4x^{3 - 9} \cdot 15 \cdot 2x^{3 - 4x} \cdot 2^{-7x}), we first combine the coefficients: (4 \cdot 15 \cdot 2 = 120). Next, we simplify the powers of (x): (x^{(3 - 9) + (3 - 4x) - 7x} = x^{-6 - 11x}). Thus, the expression simplifies to (120x^{-6 - 11x}).
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
