Answer:
3) 124
Step-by-step explanation:
a1 = 10
a2 = a1+6 = 10+6 = 16
a3 = a2+6 = a1+6+6 = a1 + 2×6 = 22
a4 = a3+6 = a2+6+6 = a1+6+6+6 = a1 + 3×6 = 28
...
=>
an = an-1 + 6 = a1 + 6(n-1)
=>
a20 = a1 + 6(20-1) = 10 + 6×19 = 10+114 = 124
Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).
