Question

7х+9х+0,32=2,72...

5у+7у-0,24=0,204....

2,4х-1,5х+47=1919...

Answer 1

7х+9х+0,32=2,72

16х+0,32=2,72

16х=2,72-0,32

16х=2,4

х=2,4/÷16

х=0,15

5у+7у-0,24=0,204

12у-0,24=0,204

12у=0,204+0,24

12у=0,444

у=0,444/÷12

у=0,037

2,4х-1,5х+47=191

0,9х+47=1919

0,9х=1919-47

0,9х=1872

х=1872/÷0,9

х=2080
