-8 + 7(6x) + 3 = -7x - 5 - 1
-8 + 42x + 3 = -7x - 5 - 1
42x - 8 + 3 = -7x - 5 + (-1)
42x - 5 = - 7x - 6
42x + 7x - 5 + 5 = - 7x + 7x - 6 + 5
49x = -1
49x/49 = -1/49
x = -1/49
y = -6x + 3 Multiply the slope by the negative reciprocal y = 1/6x + 3
Multiply the first by 3 and the second by -2
(9,6)
-6x
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
y = -6x + 3 Multiply the slope by the negative reciprocal y = 1/6x + 3
Multiply the first by 3 and the second by -2
you multiply it
(9,6)
6x+x = 7x
-6x
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
x=10
6x
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x+4=52 6x=48 x=8
It is: 3x2+6x-11 = 0
