2x+10=9+11-3x2x+10=20-3x5x+10=205x=10x=2
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x + 30 = 4x + 10 Subtracting 2x from each side, 30 = 2x + 10 Subtracting 10 from both sides 20 = 2x Dividing both sides by 2 10 = x x = 10
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
y = -2x+10
-2x+14=20 x=-3
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
10
2x+10=12 2x=2 x=1
8
2x + 10 = 182x = 8x = 4
