Question

20:(x+2)=2


(x+3):2=5

Answer 1

Răspuns:

• x = 8

• x = 7

Explicație pas cu pas:

20:(x+2)=2

x + 2 = 20 : 2

x + 2 = 10

x = 10 - 2

x = 8

(x+3):2=5

x + 3 = 5 * 2

x + 3 = 10

x = 10 - 3

x = 7

Answer 2

Răspuns:

$\frac{20}{x+2} =2\\\\20=2(x+2)\\\\20=2x+4\\\\20-4=2x\\\\x=\frac{16}{2} \\\\x=8\\\\\frac{x+3}{2} =5\\\\x+3=5*2\\\\x=10-3\\\\x=7$
