2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
3
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
