In mathematics, the expression x7 typically represents the product of x and 7, while 7x represents the product of 7 and x. In general, the order of terms in a multiplication expression does not change the result. However, in algebra, the order of terms can be important when simplifying or solving equations.
None. 7x - 1 is not equal to 7x - 7.
7x-2
If the x value changes u, then the y value changes by 7u.
7x2
8x=7x-7 x=-7
In mathematics, the symbol "x" typically represents multiplication. Therefore, "x7" means multiplying a number by 7. For example, if you have the expression 5 x 7, it would equal 35.
