Question

1. 2(×+2)-4=3+3

2. 3/×-2=28

3. 7x-48y+7=15

4. 2+3×=12+5×-1

5. 1/3×-2=12+1+×

6. 2×+1-3=12

7. ×-2-4=y(×-2)

ayuda por favor, necesito ahora mismo :'(
​

Answer 1

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
