Question

.(-2) – 6= 8
3.(…..)+2= -10
…… :4+9=3
-60:(……)-5=7
(…… +3).4= -20
-36:(……-1)+7= -2​

Answer 1

Respuesta:

$x \times ( - 2) - 6 = 8 \\x \times ( - 2) = 8 + 6 \\ x \times ( - 2) = 14 \\ x = 14 \div ( - 2) \\ x = - 7$

$3 \times x + 2 = - 10 \\ 3 \times x = - 10 - 2 \\ 3 \times x = - 12 \\ x = - 12 \div 3 \\ x = - 4$

$x \div 4 + 9 = 3 \\ x \div 4 = 3 - 9 \\ x \div 4 = - 6 \\ x = - 6 \times 4 \\ x = - 24$

$- 60 \div x - 5 = 7 \\ - 60 \div x = 7 + 5 \\ - 60 \div x = 12 \\ x = - 60 \div 12 \\ x = - 5$

$(x + 3) \times 4 = - 20 \\ x + 3 = - 20 \div 4 \\ x+ 3 = - 5 \\ x = - 5 - 3 \\ x = - 8$

$- 36 \div (x - 1) + 7 = - 2 \\ - 36 \div (x - 1) = - 2 - 7 \\ - 36 \div (x - 1) = - 9 \\ x - 1 = - 36 \div ( - 9) \\ x - 1 = 4 \\ x = 4 + 1 \\ x = 5$
