Answer:

x=6

Explanation:

Add five to both sides:2x-5+5=7+5

Simplify: 2x-5+5=7+5

2x=7+5

2x=12

Divide both side by the same factor: 2x/2=12/2

Simplify:x=12/2

divide 12 by 2 = 6

hope I helped you!!!

2x-5=7+5
+5
Cross out -5 & +5
7+5=12
Bring down 2x=12
Divide both sides of the equation by 2
x=6
