Substitute a-5 for b in equation 2a+3b= 5 to obtain the value a.

[tex]\begin{gathered} 2a+3\cdot(a-5)=5 \\ 2a+3a-15=5 \\ 5a=20 \\ a=4 \end{gathered}[/tex]

Substitute 4 for a in the equation b = a -5 to obtain the value of b.

[tex]\begin{gathered} b=4-5 \\ =-1 \end{gathered}[/tex]

So correct answer is a = 4 and b = -1.
