Question

ecuaciones 5x-9-10=3x+6​

Answer 1

5x-9-10=3x+6

5x-19=3x+6

5x-19-3x=6

5x-3x=6+19

2x=6+19

2x=25

x=$\frac{25}{2}$

2k+7=12-3k

2k+7+3k=12

2k+3k=12-7

5k=12-7

5k=5

k=1

2(x+2)-5(2x-3)=3

2x+4-5(2x-3)=3

2x+4-10x+15=3

-8x+4+15=3

-8x+19=3

-8x=3-19

-8x=-16

x=2

espero te sirva y sea de gran ayuda
