Step-by-step explanation:
2+−52=2−7
2x+\frac{-5}{2}=2x-7
Solve
1
Add
52
\frac{5}{2}
to both sides of the equation
2−52=2−7
2x-\frac{5}{2}=2x-7
2−52+52=2−7+52
2x-\frac{5}{2}+{\color{#c92786}{\frac{5}{2}}}=2x-7+{\color{#c92786}{\frac{5}{2}}}

Simplify
3
Subtract
2
2x
from both sides of the equation
4
Simplify
Result
