Answer 2

Respuesta:

$x + 5 = 15 \\ x = 10$

$2 + x = 33 \\ x = 33 - 2 \\ x = 31$

$27 = 7 + x \\ 27 - 7 = x \\ 20 = x$

$x - 22 = 34 \\ x = 34 + 22 \\ x = 56$

$x - 2 = 16 \\ x = 18$

$30 = x - 5 \\ 30 + 5 = x \\ 35 = x$

$x + 6 = 324 \div 3 \div 2 - 48 \\ x + 6 = 108 \div 2 - 48 \\ x = 54 - 48 - 6 \\ x = 0$

$x + 5 = 6 \\ x = 6 - 5 \\ x = 1$

$2x - 2 = 4 \\ 2x = 6 \\ x = \frac{6}{2} = 3$

$5x - 27 = 8 \\ 5x = 8 + 27 \\ 5x = 35 \\ x = \frac{35}{5} = 7$

$4x + 3 = 23 \\ 4x = 20 \\ x = 5$

$7x + 2 = 9 \\ 7x = 7 \\ x = 1$

$2(x + 1) = 18 \\ 2x + 2 = 18 \\ 2x = 16 \\ x = 8$

$2x + 5(25 - 20) = 7 \times 7 + 10 \\ 2x + 5(5) = 49 + 10 \\ 2x = 59 - 25 \\ 2x = 34 \\ x = 17$
