Question

1.2z-12+3z=3
2.8x-7=15+6x
solve this equation properly​

Answer 1

Answer:

• 2z-12+3z = 3

2z+3z = 3 + 12

5z = 15

z = 15 ÷5

z = 3

• 8x (-7) = 15 + 6x

8x-6x = 15+7

2x = 22

x = 22÷2

x = 11

Answer 2

Answer:

1.z=3

2.x=11

Explanation:

1.2z-12+3z=3

:2z+3z-12-3=0

:5z-15=0

:5z=15

:z=15/5

:z=3

2.8x-7=15+6x

:8x-6x=15+7

:2x=22

:x=22/2

:x=11

hope this is correct
