[tex](2x+1)+(x-10)=90\\\\(2x+x)+(1-10)=90\\\\3x-9=90\ \ \ |+9\\\\3x=99\ \ \ |:3\\\\x=33^o[/tex]

Yes. The equation make sense. It's has the solution.

[tex]x=33^o\\\\2x+1=2(33)+1=67^o\\\\x-10=33-10=23^o[/tex]

Since both angles are positive angles, hence we can conclude that the equation given makes sense.

Given the expression ( 2x + 1°) + ( x - 10°) = 90°

In order to know if it makes sense, we first need to get the unknown variable "x" as shown:

2x + 1 + x - 10 =90

3x - 9 = 90

3x = 90 + 9

3x = 99

x = 33

Get the individual angle

For 2x + 1

2(33) + 1

= 66 + 1

= 67

For x - 10

33 - 10 = 23

Since both angles are positive angles, hence we can conclude that the equation given makes sense.
