170+540÷х=260 100+ х÷40=115

Question

170+540÷х=260 100+ х÷40=115

Answer 1

1) 170 + 540 : х = 260
540 : х = 260 - 170
540 : х = 90
х = 540 :90
х = 6

2) 100 + х : 40 = 115
х : 40 = 115 - 100
х : 40 = 15
х = 15 * 40
х = 600

Answer 2

540:x=260-170
540:x=90
X=540:90
X=6.






100+x:40=115
X:40=115-100
X:40=15
X=15*40
X=60
