Hey there!
This equation has infinite solutions.
To solve for this equation, first add -7 to both sides in order to get rid of the constant:
2x-2x-7=-7
2x-2x=0
Now, combine your like terms or add 2x and -2x together:
2x-2x=0
0=0
Because you result in a true mathematical statement (0 is equal to itself), you have an infinite amount of solutions or all real solutions.
To check if this is true, plug in any number in place of x in the original staeltement to see if you result in a true statement:
Let's say x is 5
2(5)-2(5)-7=-7
10-10-7=-7
-7=-7
This proves that you have infinite solutions for your equation. :)

Answer:</h2><h2>x=37.5° and angle ABC is 52.5°</h2><h2>
Step-by-step explanation:</h2>
We know that angle CBD is a right angle.
We also know that angle ABE is 180°.
Our unknown angle values are angle DBE and angle CBA.
angle CBD minus angle ABE will be 90°.
angle ABC plus angle DBE must equal 90°.
Solving for x:
(x+15)+(x)=90°
(x+15-15)+(x)=90°-15
(x)+(x)=75°
2x=75°
2x/2=75°/2
x=37.5°
Checking the work:
ABC=37.5°+15=52.5°
CBD=90°
DBE=37.5°
In conclusion, ABC plus CBD plus DBE equals 180°
