Question

5×+5×=1500
50×+10=150010
25×-10=40

Answer 1

Explicação passo-a-passo:

10x = 1500

x = 1500/10

x = 150

50x = 150010 - 10

50x = 150000

x= 3000

25x = 40 +10

x = 50/25

x = 2

Answer 2

A)x=150

B)x=300

C)x=2

Explicação passo-a-passo:

A)5x+5×=1500

5x+5x=1500

5x+5x

(5+5)x

10x

5x+5x=1500

10x=1500

10x÷10=1500÷10

x=1500÷10

10x÷10=1500÷10

x=150

10x=1500

x=150

Resposta

x=150

B)50x+10=150010

50x+10=150010

50x+10-10=150010-10

50x=150010-10

50x+10=150010

50x=150010-10

50x=150000

50x÷50=150000÷50

x=150000÷50

50x÷50=150000÷50

x=3000

50x=150000

x=300

Resposta

x=300

C)25x-10=40

25x-10=40

25x-10+10=40+10

25x=40+10

25x-10=40

25x=40+10

25x=50

25x÷25=50÷25

x=50÷25

25x÷25=50÷25

x=2

25x=50

x=2

Resposta

x=2
