Answer 1

Explicação passo-a-passo:

2×+×=12

3×=12

×=12/3

×=4

5×-20=40+2×

5x-2×=40+20

3×=60

×=60/3

×=20

50+3×-4=6×-8+26

3×-6×=26-8+4-50

-3×=-58+30

-3×=-28(-1)

3×=28

×=28/3

×=9,33

×/2+4×=15+×-90mmc(2)

2×+8×=30+2×-180

10×-2×=-180+30

8×=-150

×=-150/8

×=18,75

4×-8=5×/2+20mmc(2)

8×-16=5×+40

8×-5×=40+16

3×=56

×=56/3

×=18,66
