Question

A x/5+x/3=8

B X/2+X/6=4

C X/8+X/6=7

Answer 1

Explicação passo-a-passo:

A x/5+x/3=8

3.x+5.x/5.3=8

3x+5x/15=8

8x/15=8

8x=8.(15)

8x=4.(30)

8x=120

x=120/8

x=60/4

x=15

B X/2+X/6=4

2.x+6.x/2.6=4

2x+6x/12=4

8x/12=4

8x=4.(12)

8x=48

x=48/8

x=6

C X/8+X/6=7

8.x+6.x/6.8=7

8x+6x/48=7

14x=7.(48)

14x=336

x=336/14

x=24

espero ter ajudado!

boa tarde !

Answer 2

a) x/5 + x/3 = 8

3x + 5x / 15 = 8

3x + 5x = 8 * 15

8x = 120

x = 120/8

x = 15

b) x/2 + x/6 = 4

6x + 2x / 12 = 4

6x + 2x = 4 * 12

8x = 48

x = 48/8

x = 6

c) x/8 + x/6 = 7

6x + 8x / 48 = 7

6x + 8x = 7 * 48

14x = 336

x = 336/14

x = 24
