4x-7x = -3
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
4x + 8 + 7x + 12 = 11x + 20
4x+5=7x-8 the ansewr is 3.25
4x + 8
Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
7x = 4x - 93x = -9x = -3
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
3x-8
-14x^2+13x-5
