7x + y = 4y = 4 - 7x
-7x + 6 + 7x - 2 = 4
6 = 7x + x First, add 7x and x.6 = 8xNow, divide both sides by 8.6/8 = xSimplify the answer.3/4 = x.
7x-4=9x+10-14=2xx=-7
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
7x + y = 4y = 4 - 7x
7x+17 = 45 7x = 45-17 7x = 28 x = 4
7x=2x-4 5x=-4 x=-4/5
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
There is no symbol between 7x and 31. Please resubmit using words eg "plus", "equals" etc.
7x/4 = 1/8 (7x/4) x (8) = (1/8) x (8) 14x = 1 x = 1/14
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
If you mean 3x2-7x+x = -4 then there are no solutions because the discriminant of the quadratic equation is less than zero.
-7x + 6 + 7x - 2 = 4
7x - 4 = 60 7x = 64 x = 9.14
6 = 7x + x First, add 7x and x.6 = 8xNow, divide both sides by 8.6/8 = xSimplify the answer.3/4 = x.
assuming the gap before x-2 is a +, then x+x-2=7x, so 2x-2=7x, so 5x=-2, so x=-.4
