Verified answer
1. 2(×+2)-4=3+3
2x + 4 -4=6
2x = 6
x = 3
2. 3/×-2 = 28x
3/x=30.
3 = 30x.
x = 3/30.
x = 1/10.
3. 7x- 48y+7 =15
7x - 48y = 8
4. 2 + 3× = 12 + 5× - 1
2 + 1 - 12 = 5x - 3x
- 9 = 2x
x = -9/2
5. 1/3×-2 = 12+ 1 + ×
1/3x = 15 + x
1 = 45x + 3x^2
1 = x(45 + 3x)
6. 2× +1 -3 = 12
2x-2 = 12
2x = 14
X = 7
7. ×-2-4=y(×-2)
x -6 = xy - 2y
-6 = xy - 2y - x
- 6 = y(x - 2) - x
