Answer:
[tex]17\ stickers[/tex]
Step-by-step explanation:
Let
x-----> number of stickers Liam has
y-----> number of stickers Jade has
we know that
[tex]x=3y[/tex] -----> equation A
we have
[tex]x=51\ stickers[/tex]
substitute the value of x in the equation A and solve for y
[tex]51=3y[/tex]
[tex]y=51/3[/tex]
[tex]y=17\ stickers[/tex]
