Question

URGENT!!!!
CAT FACE 3(x-1)+1=4 ; 7(x+2)-5=44 : 10-3(x-1)=44

Answer 1

3(x-1)+1=4
x=2

7(x+2)-5=44
x=5

10-3(x-1)=44
x=31,3

Nu cred ca ultima am rezolvat-o corect, scz

Answer 2

3(x-1)+1=4
3x-3+1=4
3x-3=4-1
3x=3+3
3x=6
x=6:3
x=2


7(x+2)-5=44
7x+14-5=44
7x+14=44+5
7x+14=49
7x=49-14
7x=35
x=35:7
x=5


10-3(x-1)=44
aici ceva nu e bine! indiferent ce scazi din 10 nu are cum sa iti dea 44! cred!
