(7 x 4) + (3 x 4) = 10 x 4 = 40
x = 7
Depends on where the parentheses are. X(7-4) + X7 + 4 = 10X + 4 X(7-4) + X(7+4) = 14X
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
It is: x+4+2x-7 = 3x-3 simplified

2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
2x + 7 = x + 3 x + 7 = 3 x = -4
x2+14x+40 = (x+4)(x+10) when factored
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84
(x + 10) and (x + 4) are both factors
