Let the number be x and so the expression is 8x
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
8(30) - 40 = 240 - 40 = 200.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.

8(x + 1)
Let the number be x and so the expression is 8x
To simplify the expression 8x - 8 - 4x - 3 - 3x, first combine like terms. Start by combining the x terms: 8x - 4x - 3x = x. Then, combine the constant terms: -8 - 3 = -11. Therefore, the simplified expression is x - 11.
Well, isn't that just a happy little question! When we have 8x for each value of x, it simply means we are multiplying 8 by whatever value x represents. So, if x is 2, then 8 times 2 equals 16. Just remember to let your imagination flow and enjoy the process of discovering the beauty in mathematics!

abs(8x - 7)
It is: 29+8x
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
x * -8 = -8x
8x + x = 9x
8(30) - 40 = 240 - 40 = 200.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
