Question

me ayudaaaaaaannnnn.....​

Answer 1

Explicación paso a paso:

A)

$x + 1 = 7 \\ x = 7 - 1 \\ x = 6$

B)

$x + 2 = 8 \\ x = 8 - 2 \\ x = 6$

C)

$x + 1 = 7 \\ x = 7 - 1 \\ x = 6$

D)

$x + 17 = 52 \\ x = 52 - 17 \\ x = 35$

E)

$2 \times x = 8 \\ 2x = 8 \\ x = \frac{8}{2} \\ x = 4$

F)

$3 \times x = 12 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$

G)

$\frac{x}{5} = 4 \\ x = 4 \times 5 \\ x = 20$

H)

$2x + 6 = 12 \\ 2x = 12 - 6 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

I)

$\frac{10}{x} = 2 \\ 10 = 2 \times x \\ 10 = 2x \\ \frac{10}{2} = x \\ 5 = x$

$3 \times x = 21 \\ 3x = 21 \\ x = \frac{21}{3} \\ x = 7$
