Answer 1

Respuesta:

$5 \times (a + 3) = 45 \\ 5a + 15 = 45 \\ 5a = 45 - 15 \\ 5a = 30 \\ a = 30 \div 5 \\ a = 6$

$8 \times (p + 4 ) + 3p - 2p = 5 \times 8 + 1 \\ 8p + 32 + 1p = 40 + 1 \\ 9p + 32 = 41 \\ 9p = 41 - 32 \\ 9p = 9 \\ p = 9 \div 9 \\ p = 1$

$- 5 \times (x - 2) + 4 = - 3( - x - 2) \\ - 5x + 10 + 4 = 3x + 6 \\ - 5x + 14 = 3x + 6 \\ 14 - 6 = 3x + 5x \\ 8 = 8x \\ 8 \div 8 = x \\ 1 = x$

$3 \times ( \times - 2) = - 3 \\ 3x - 6 = - 3 \\ 3x = - 3 + 6 \\ 3x = 3 \\ \times = 3 \div 3 \\ x = 1$
