2x/5+3=7

2x/5=7-3
2x/5=4
2x/5*5=4*5
2x=20
2x/2=20/2
x=10

Be sure to use this way for math problems similar to this one

2x / 5 + 3 = 7

2x / 5 + 3 - 3 = 7 - 3

2x / 5 = 4

8(2x/5) = 5(4)

2x = 20

2x/2 = 20/2

x = 20/2

x = 10

2x/5 + 3 = 7
2x/5 +3 -3 = 7 - 3
2x/5 = 4
2x/5 * 5 = 4* 5
2x = 20
x = 10
Good luck.
