7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
7x + 5 + 3x is [ 10x + 5 ].That's the same thing as [ 2 times (5x + 1) ] .
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
10x + 5 which is also equal to 5(2x + 1)
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
7x + 5 + 3x is [ 10x + 5 ].That's the same thing as [ 2 times (5x + 1) ] .
-3x + 10x - 5 + 26 = 7x + 21
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
6x2 + 7x - 5 = (3x + 5)(2x - 1)
10x + 5 = 5(2x + 1)
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
10x + 5 which is also equal to 5(2x + 1)
Factorise it: (x + 5)(3x - 8)
