Question

Ajutatima varog la ecuatii:14x+28x=588 2. 9 (2x+1)=153 3. 3 (2x+5)+19=82 4. 9 (5-3x)+71=89 Urgent!!!!!!

Answer 1

14x+28x=588
42x=588
X= 588:42
X= 14

9(2x-1) = 153
18x+9=153
18x = 153-9
18x= 144
X=144:18
X= 8

3(2x+5)+19=82
6x+15+19=82
6x+34=82
6x=82-34
6x=48
X=48:6
X=8

9(5-3x)+71=89
45-27x+71=89
-27x+116=89
-27x=89-116
-27x=-27
X= -27: (-27) = 1

Answer 2

1.Aduni 14x cu 28x si apoi il imparti pe 588 la 42x si x=14,2.la urmatorul scrii 153:9=17 iti ramane 2x+1=17 si 17 -1=16 si 16:2=8 x=8 3.82-19=63:3=21 2x+5=21,21-5=16 16:2=8 x=8
