If you meant (-7 x 4) - (2 x -8) then the answer is (-28) - (-16) = -28 + 16 = -12
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
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
42 x 8 = (40 x 8) + (2 x 8) = 320 + 16 = 336
7x-6w = 1
4x-7x = -3
