Question

1) 5x - 5 = 15 - 5

2) 2= x : 900

3) x/5 - 6 = 9- 3

4) 15 = t + 2 + 4

5) 8f + 3 = 19

¡Hola!

Explicación paso a paso:

1)

$5x - 5 = 15 - 5 \\ 5x = 15 - 5 + 5 \\ 5x = 15 \\ x = 15 \div 5 \\ x = 3$

2)

$2 = x : 900 \\ 2 \times 9000 = x \\ 18.000 = x$

3)

$\frac{x}{5} - 6 = 9- 3 \\ \frac{x}{5} = 9 - 3 + 6 \\ \frac{x}{5} = 12 \\ x = 12 \times 5 \\ x = 60$

4)

$15 = t + 2 + 4 \\ 15 - 2 - 4 = t \\ 9 = t$

5)

$8f + 3 = 19 \\ 8f = 19 - 3 \\ 8f = 16 \\ f = 16 \div 8 \\ f = 2$

6)

$6h + 5 = 20 + 3h \\ 6h - 3h = 20 - 5 \\ 3h = 15 \\ h = 15 \div 3 \\ h = 5$

Espero que te sirva, Salu2!
