X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)
Because of the minus sign, 8 turns to -8, -8x3=-24.
(2x - 7)(x + 1)
7+x=15 x=8
[ x3 - 4x2 + 7x ] / (x) = x2 - 4x + 7
If X - 8 = -1 then X = -1 +8 Therefore X = 7
X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)
square root of 8
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
X - 7 = 11 X = 11+7 therefore X = 18 18 minus 7 equals 11.
(-8) x (-7) - 14 = 42
X + y = 8 x - y = 6 add equations to eliminate y 2x = 14 x = 7 substitute 7 + y = 8 y = 1
x=1
6
15
14
X = 2, 2 X 2 X 2 = 8 - 8 = 0
