Question

solve step by step and explain ​

Answer 1

Step-by-step explanation:

1. 2x-5=x+7

x=12

24-5=19

12+7=19

2. 6y+1=4y+9

2y=8

y=4

24+1=25

16+9=25

Answer 2

Step-by-step explanation:

2x-5 = x+7 ( Diagonals bisect each other and are equal )

2x-x-5 = 7

x -5 = 7

x = 7+5

x = 12

Therefore, 2x+5 = 2×12+5 = 29

x +7 = 12+7 = 19

6y+1 = 4y+9 (Diagonals bisect each other and are equal)

6y-4y+1= 9

2y+1 = 9

2y = 9- 1

2y = 8

y = 8/2 = 4

y = 4

Therefore, 6y +1 = 6×4+1 = 25

4y+9 = 4×4+9 = 45
