Gaseste valorile necunoscutelor m,n,p:
136×12+2×m=1605
36÷p+324×22=7137
279×25+n×5=7010
64÷r+530×18=9548
Va rog frumos sa ma ajuati

Answer 1

136x12+2xm=1605 => 1633+2xm=1605 => 2xm=1605-1633 => 2xm= -28 => m= -28÷2 => m= -14 36÷p+324x22=7137 => 36÷p=7137-7128 => 36÷p=9 => p=36÷9 => p=4 279x25+nx5=7010 => nx5=7010-6975 => nx5=35 => n=35÷5 => n=7 64÷r+530x18=9548 => 64÷r=9548-9540 => 64÷r=8 => r=8
