Watch closely:It's 7x
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7

49x²+70x+25 = (7x+5)² since the root (-70/(2*49)) of the quadratic equations is -5/7 (discriminant = 70²-4*49*25 = 0)

Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
If you mean: 7x = 49 then the value of x is 7
7x7=49
7x2 plus 7x5 = 49
7x
-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
Factoring involves 'factoring out' the common numbers for each term. In a simple general form, a + ab = a(1+b). It's like "undistributing" factors: instead of multiplying both terms by a number, you essentially divide both terms by a number. In (7x + 49), both terms - 7x and 49 - have 7 as a factor. So, it can also be written: 7x + 49 = 7(x+7)
1,2,7,14 1,7,49
If 7x - 5 = 44 Then 7x = 44 + 5 = 49 x = 49/7 Therefore, x = 7
