1. Convert equation according to b, insert the part of the first equation, which is equal to b, into the second equation, then a value for a comes out. Use this for a in one of the equations and calculate b

I must have the following equation 1. 3a-b=3.5 and 2. -b=-6a+5, with the equation

Convert both equations, for example, to -b.

and recruitment procedures
