Answer: x + y = 21...... Equation 1 and
2x = y....... Equation 2
Explanation: let x be the number of 2 points shots
While y be the number of 3 point shots
A total of the 2 point shots and the 3 point shots equals 21.(equation 1)
Also if 2 point shots is twice 3 point shots it means 2x=y.(equation 2).
To know the number of 2 point shots, simply substitute y in equation 1 with equation 2.
That is x + 2x = 21
X(1 + 2) = 21
3x= 21
X = 21/3
X = 7
Substitute the value of x in equation 2
2(7) = y
14 = y
Answer:
part 1:
let x be the number of two point shots made
let y be the number of three point shots made
the equations are:
y=2x
2x+3y=21
Explanation:
Every two-pointer he gets is 2x. Every 3 pointer he gets would be 3x. In total we are told he scored 21 points. This means the equation must look like:
2x+3y=21
We are given that for every three-point shot (y) made he doubles it with a 2 point shot (x). This tells us that for every, one shot he makes of y it is doubled by x.
the second equation would look like 2x=y or y=2x
