8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 8!
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
4 x 8 - 2 = 32 - 2 = 30
Y = 4 (x+8)
-4 (-9 +5 = -4)
8!
2(x + 4) or 2(x - 4) depending on the missing operational sign.
8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 8!
40 + 32 = (5 x 8) + (4 x 8) = 9 x 8 = 72
If your expression is 5x + 4 = ? and x = 3, then the answer is 19. If the expression is 5(x + 4) = ? and x = 3, then the answer is 35.
4*(x - 8)
5 x -4
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
(45) x (43) = 48
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
To simplify the expression 16x - 8 - 5 - 6x - 4, first combine like terms. Combine the x terms by subtracting 6x from 16x to get 10x. Then, combine the constants by adding -8, -5, and -4 to get -17. Therefore, the simplified expression is 10x - 17.
