Question

A) 397+42 × m =859 b) 974-124÷n=943 c) 40×p-500=300 va rog ajutatima rapid

Answer 1

a)
397 + 42 × m =859
42 × m = 859 - 397
42 × m = 462
m = 462 : 42
m = 11

 b)
974 - 124 : n = 943
124 : n = 947 - 943
124 : n = 4
n = 124 : 4 
n = 31

 c)
40 × p - 500 = 300
40 × p = 300 + 500
40 × p = 800 
p = 800 : 40 
p = 20
