Answer 1

a) 173 + 2÷2 - 6x = 6
=> 173+ 1 -6x =6
=>174 -6x =6
=> 6x= 174+6
=> 6x= 180
=> x = 180 ÷ 6
=> x= 30
b) 339 +341 ÷31 - 19x =27
=>339+ 11 -19x = 27
=>350 - 19x = 27
=> 19x= 350 -27
=> 19x= 323
=> x= 323 ÷ 19
=> x= 17
c) 94 + 448 ÷ 16 -20x= 42
=>94 + 28 - 20x = 42
=>122 - 20x = 42
=> 20x= 122 +42
=> 20x= 164
=> x= 164 ÷ 20
=> x = 8.2
