10x ÷ 2 = 7 → 10x = 2 × 7 → x = (2 × 7) ÷ 10 → 2x = 2 × (2 × 7) ÷ 10 = 2.8
2x+52=0 =>2x= -52 =>x= -52/2 =>x= -26
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
-3(x-5)=2x
6 - (2 x 7) - (3 x (-9)) = 19
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
2x+52=0 =>2x= -52 =>x= -52/2 =>x= -26
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
6 - (2 x 7) - (3 x (-9)) = 19
x=7
3X - 1 = 2X + 6 => Bring the 2X to the left X - 1 = 6 => Bring the -1 to the right X = 7
The given expression is x + 6 = 2x + 5. Subtract both sides by x to get: x - x + 6 = 2x - x + 5 6 = x + 5 Subtract both sides by 5 to get: 6 - 5 = x + 5 - 5 x = 1

6 + 2x = x - 6 2x - x = -6 -6 x = -12
