You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
D, since X has only one box and is negative.
20 x 10 = 200 and 2 x 2= 4 and 200 x 4 = 800, or
20 x 10 x 2 x 2= 800

Answer: t₇ = 17 t₃₀ = 63 S₁₀ = 140
<u>Step-by-step explanation:</u>
t₇ = 2(7) + 3
= 14 + 3
= 17
t₃₀ = 2(30) + 3
= 60 + 3
= 63
S₁₀ = (t₁ + t₁₀)/2 × 10
= (5 + 23)/2 × 10
= 28/2 10
= 14 × 10
= 140
