Question

The value of y or how do I solve it

Answer 1

Any straight line has associated a 180° angle, according to the this the addition of the angles shown, which can also be named as supplementary angles.

according to this we can write the equation

`(2y+1)+(5y-3)=180`

solve the equation for y

`\begin{gathered} 7y-2=180 \\ 7y=180+2 \\ 7y=182 \\ y=(182)/(7) \\ y=26 \end{gathered}`
