- 7x + (9x - 3) = - 7x + 9x - 3 = 2x - 3
3x+7x+3+y= 10x+3+y
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
The answer to the math problem -3 7x plus 7 is x equals 1/3.
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
3+3x+7x=13 3x+7x=10 10x=10 x=1
7x + 3
-7x - 2y = -3
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
the answer is 0
Why not? The statement is trivially true, meaning it holds for all values of x.
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
