Answer:
[tex]a=7[/tex]
Step-by-step explanation:
we have
[tex]7(a-10)=13-2(2a+3)[/tex]
Solve for a
[tex]7a-70=13-4a-6[/tex]
Group terms that contain the same variable and move the constants to the other side
[tex]7a+4a=13-6+70[/tex]
Combine like terms
[tex]11a=77[/tex]
Divide by [tex]11[/tex] both sides
[tex]a=7[/tex]
