Question

10+8×=50?
×+8+3×=24?
3a-12+a=+12
3×+8-×=10?
y-12=8?
me ajude

Answer 1

10+8x = 50
8x = 50-10
8x = 40
x = 40/8
x = 5

x+8+3x = 24
x+3x = 24-8
4x = 16
x = 16/4
x = 4

3a-12+a = 12
3a+a = 12+12
4a = 24
a = 24/4
a = 6

3x+8-x = 10
3x-x = 10-8
2x = 2
x = 2/2
x = 1

y-12 = 8
y = 8+12
y = 20

Espero ter te ajudado !!

Answer 2

10+8×=50

8x = 50 - 10

8x = 40

x = 40/8

x = 5

×+8+3×=24

4x = 24 - 8

4x = 16

x = 16/4

x = 4

3a-12+a=+12

4a = 12 + 12

4a = 24

a = 24/4

a = 6

3×+8-×=10

2x = 10 - 8

2x = 2

x = 2/2

x = 1

y-12=8

y = 8 + 12

y = 20
