Answer:
x=6 y=7
(6,7)
Step-by-step explanation:
y=x+1 5x+3y=51
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
substitute
y=6+1
add like terms
y=7
