Answer:
x:y:z = 12:3:2
Step-by-step explanation:
x = 4y
2y = 3z ⇒ 4y = 6z
⇒ x = 4y = 6z
To find x:
Multiply the coefficients of y & z: 4 × 6 = 24
To find y:
Multiply the coefficients of x & z: 1 × 6 = 6
To find z:
Multiply the coefficients of x & y: 1 × 4 = 4
⇒ x:y:z = 24:6:4 = 12:3:2
Answer:
no, no, yes, no
Step-by-step explanation:
3x + 7y = 17
1. 3(5) + 7(3) = 17 ---> 15 + 21 = 17 (false)
2. 3(-8) + 7(-2) = 17 ---> -27 + -14 = 17 (false)
3. 3(-6) + 7(5) = 17 ---> -18 + 35 17 (true)
4. 3(8) + 7(-1) = 17 ---> 18 + -7 = 11 (false)
