Answer:
y = 21, x = 6
Step-by-step explanation:
Substitute y = 7x - 21
7x - 21 = x + 15
Isolate x for 7x - 21 = x +15
x = 6
For y = 7x - 21
Substitute x = 6
y = 7 * 6 - 21
Simplify
y = 21
Answer:
8 two-point shots,
4 three-point shots
Step-by-step explanation:
let 'x' = 2-pt shots
let 'y' = 3-pt shots
system of equations can be used as follows:
x + y = 12
2x + 3y = 28
if we solve for 'y' we get 'y = 12-x'
use '12-x' instead of 'y' in the equation 2x + 3y = 28 to solve for 'x':
2x + 3(12-x) = 28
2x + 36 - 3x = 28
-x + 36 = 28
-x = -8
x = 8
if x+y = 12, then y = 4
