The complete question is
Susan and Steven are cousins. The sum of their ages is 33. The difference between three times Steven's age and half of Susan's age is 36. Find the age of Susan and Steven

let
x> Susan's age
y>  Steven's age

we know that
y+x=33> equation 1
3y-x/2=36> multiply by 2> 6y-x=72> equation 2
adds equation 1 and equation 2

y+x=33
6y-x=72
+
7y=105> y=15
x=33-y> x=33-15> x=18

the answer is
Susan's age is 18
Steven's age is 15

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
