Answer:

The solution for the equation is [tex]x = 4[/tex] .

Step-by-step explanation:

-Solve the equation:

[tex]2x +5=7x -15[/tex]

-Subtract 7x from 2x:

[tex]2x +5 -7x=7x -7x -15[/tex]

[tex]-5x + 5=-15[/tex]

-Subtract both sides by 5:

[tex]2x + 5 - 5 = -15 -5[/tex]

[tex]-5x = -20[/tex]

-Divide both sides by -5:

[tex]\frac{-5x}{-5} = \frac{-20}{-5}[/tex]

[tex]x = 4[/tex]

So, the answer is [tex]x = 4[/tex] .
