Question

1. 5A + 2 = 17 2. 3B - 5 = B + 3 3. 5X = 8X - 15 4. 4Y + 1 = 2 ayuda porfar son ecuaciones

Answer 1

Respuesta:

1. 5a + 2 = 17

5a = 17 - 2

5a = 15

a = 15 ÷ 5

a = 3

2. 3b - 5 = b + 3

3b - b = 3 + 5

2b = 8

b = 8 ÷ 2

b = 4

3. 5x = 8x -15

5x - 8x = -15

-3x = -15

x = -15 ÷ (-3)

x = 5

4. 4y + 1 = 2

4y = 2 - 1

4y = 1

y = 1 ÷4

y = 0,25 = $\frac{1}{4}$
