Question

AJUTATI-MA VA ROG LA ECUATIILE- 5X+1=22,3X-7=10,2X+3X=35 EXPLICATI

Answer 1

5x+1=22
5x=22-1
5x=20
x=20:5
x=4
3x-7=10
3x=10+7
3x=17
x= 17 pe 3
2x+3x=35
5x=35
x=35:5
x=7

Answer 2

$\displaystyle a).- 5x+1=22 \\ -5x=22-1 \\ -5x=21 \\ x=- \frac{21}{5}$
$\displaystyle b).3x-7=10 \\ 3x=10+7 \\ 3x=17 \\ x= \frac{17}{3}$
$\displaystyle c).2x+3x=35 \\ 5x=35 \\ x= \frac{35}{5} \\ x=7$
