Question

10 ×-10=5(×+2)
4(×+5)=2×+34
10(×+2)=8×+22​

Answer 1

Respuesta:

1) 10×-10=5(×+2)

10x -10 = 5x + 10

10x -5x = 10+10

5x =20

x =4

2) 4(×+5)=2×+34

4x + 20= 2x+ 34

4x- 2x= 34- 20

2x= 14

x=7

3) 10(×+2)=8×+22

10x +20 =8x +22

10x - 8x =22-20

2x=2

x=1

4) 5(×+4)=3(×+10)-8

5x +20x =3x+30-8

5x + 20 =  3x+22

5x - 3x = 22-20

2x = 2

x=1
