Question

resolva ecuatiile [(8×2+6× x):2-48]×3=186 ;10 ×[5+3×(16-3x)]-35×2=100 day Coronitaza repede

Answer 1

[(16+6x):2-48]=186:3
(16+6x):2=62+48
16+6x=110×2
6x=220-16
6x=204
x=204:6
x=34
10×[5+3×(16-3x)]-35×2=100
10×[5+3×(16-3x)]=100+70
[5+3×(16-3x)]=170:10
3×(16-3x)=17-5
16-3x=12:3
-3x=4-16
3x=12
x=4
