​

Răspuns:

5×(x+3)=2×(5x-5)

5x+15=10x-10

15+10=10x-5x

5x=25

x=25:5

x=5

Răspuns:[tex]\bf \red{ \underline{x = 5}}[/tex]

Explicație pas cu pas:

[tex] \bf 5 \cdot(x+3)=2 \cdot(5x-5)[/tex]

[tex]\bf 5x+15=10x-10[/tex]

[tex]\bf 5x+15 + 10 =10x[/tex]

[tex]\bf 5x+25 =10x[/tex]

[tex]\bf 25 =10x - 5x[/tex]

[tex]\bf 25 =5x[/tex]

[tex]\bf x = 25: 5[/tex]

[tex]\bf \red{ \underline{x = 5}}[/tex]
