That doesn't look quite right. As written, that's 4x + 61, which doesn't factor. If you meant 4x2 + 49x + 12, the answer is (4x + 1)(x + 12)
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
If you mean 49+6 = 4x-7 then the value of x is 15.5
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
-11
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
the answer to this is 4x + 57 (assuming that the 4x in the question is algebra)
4x + 8 + 7x + 12 = 11x + 20
8x + 15
It is: y = -4x+12
If: 4x+(-12) = 8 then 4x = 20 and x = 5
4[x+3]=4x+12 4x+12=4x+12 it's open.
2x + 6x + 4x = 12x
