to solve this you can use the substitution method or anotherone i forgot the name of. so in with that being said, the substitution method is the wa to go.

start with the first equasion

5x+3y=51

substitute

5x+3(x+1)=51

distribute

5x+3x+3=51

add like terms

8x+3=51

solve equasion

8x=48

x=6

now onto the next equasion

y=x+1

Answer:

-4

Step-by-step explanation:

$\left( \dfrac{1}{9}\right)^{a+1}= 81^{a+1}\cdot 27^{2-a}\\\\\\(3^{-2})^{a+1}=(3^4)^{a+1}\cdot (3^3)^{2-a} \\\\\\3^{-2a-2}=3^{4a+4}\cdot 3^{6-3a} \\\\\\3^{-2a-2}=3^{a+10} \\\\\\-2a-2=a+10 \\\\\\-3a=12 \\\\\\a=-4$
