Question

Aflati x din egalitatile:
a) 13*5+x+173=2(159+7*36)
b) 14*7+2x+122=4*(52+12*15)
c) 15+143+2*(x+3)=2*(15-7*2)*100+18*36
d) 28+2030+2*(x+5)=3*(81-7*5)*101
e) (350+x)*16=8224
f) (256+3x+2x)*12=4272
g) [(x-28*2)*3+5]*12=1644

Answer 1

a. 65 + x+ 173 = 318 + 504
x = 822- 238
x= 584

b. 98 + 2x + 122 = 208 +720
2x= 928 - 220
2x = 708
x= 354

c. 158 + 2x + 6 = 24300 - 2800 + 648
2x = 22148 - 164
2x =21984
x = 10992

d. 2058 + 2x + 10 = 24543- 10605
2x = 13938 - 2068
2x = 11870
x = 5935

 e. 5600+ 16x = 8224
16x= 8224 - 5600
16x = 2624
x =164
 
f. 3072 +36x + 24x = 4272
60x = 4272 - 3072
60x = 1200
x= 20

g. ( 3x - 168 + 5) * 12 = 1644
36x - 2016 + 60 = 1644
36x = 1644 + 1956
36x = 3600
x = 100

Sper ca te-am ajutat !!
