Question

(23-x):6=3 5·(3·x-9)=60 (23-5·x):9=2 24:(5-x)=6 32:(13-5·x)=4 3·x-15:3=19+3 5·x-21:7=4+13 13-14:x=18-7 x+5·(33+128)=895 x-53·(49-3·12)=996 53+2·x=x+111 23+5·x=2·x+74 32+6·x=11·x-113 8+13·x=2·x+41

Answer 1

23-x=6×3 ➡23-x=18 ➡x=23-18 ➡x=5

5(3x-9)=60➡15x-45=60➡15x=60+45➡
15x=105 ➡x=7

(23-5x) :9=2➡23-5x=2×9 ➡23-5x=18➡
5x=23-18➡ x=1

23:(5-x) =6➡5-x=6×23➡5-x=138 ➡x=143

32:(13-5x) =4 ➡13-5x= 4×32 ➡13-5x=128
5x=128-13 ➡5x=115 ➡x=25

Restul se fac la fel
