giúp mình với mình đang cần gấp ạ
cảm ơn <3 <3 <3.
a) 5x + 2x = 62 - 50
b) 5x + x = 150 : 2 + 3
c) 6x + x = 511 : 59 + 31
d) 5x + 3x = 36 : 33.4 + 12
4x + 2x = 68 – 219 : 216
1) 168 - ( 18 - 2x ) x 12 = 120
2) [ 75 + ( 16 - x ) ] x 2 = 156
3) 124 - 24 x ( 3x - 16 ) = 76
4) [ ( 10 - x ) x 2 + 5 ] : 3 - 2 = 3
5) [ 80 + ( 62 - x ) ] : 17 - 7 = 1
6) 65 - ( 5x - 70 ) : 2 = 50
