Question

реши уравнения.5*х=95,х*13=52,х:10=6,у*4=4,у:18=4,91:у=13

Answer 1

$5 \times x = 95 \\ x = 95 \div 5 \\ x= 19 \\ \\ x \times 13 = 52 \\ x = 52 \div 13 \\ x = 4 \\ \\ x \div 10 = 6 \\ x = 6 \times 10 \\ x = 60 \\ \\ y \times 4 = 4 \\ y = 4 \div 4 \\ y = 1 \\ \\ y \div 18 = 4 \\ y = 4 \times 18 \\ y = 72 \\ \\ 91 \div y = 13 \\ y = 91 \div 13 \\ y = 7$
