Repede va roggg​

Answer 1

$a) \: - 5x = 15 = > x = 15 \div ( - 5) = > x = - 3 \\ b) \: - 3x = - 12 = > x = - 12 \div ( - 3) = > x = 4 \\ c) \: 6x = - 18 = > x = - 18 \div 6 = > x = - 3 \\ d)x \div ( - 2) = 9 = > x = 9 \times ( - 2) = > x = - 18 \\ e)x \div ( - 5) = - 12 = > x = - 12 \times ( - 5) = > x = 60 \\ f)9x = 72 = > x = 72 \div 9 = > x = 8 \\ g)18 \div ( - x) = 6 = > - x = 18 \div 6 = > - x = 3 = > x = - 3 \\ h) - 19 \div x = 1 = > x = - 19 \div 1 = > x = - 19 \\ i)48 \div x = 24 = > x = 48 \div 24 = x = 2 \\ j)24 \div ( - x) = 6 = > - x = 24 \div 6 = > - x = 4 = > x = - 4 \\ k) - 36 \div ( - x) = 4 = > - x = - 36 \div 4 = > - x = - 9 = > x = 9 \\ l)56 \div x = ( - 28) = > x = 56 \div ( - 28) = > x = - 2$
