Answer:
y = 5 and y = 1
Step-by-step explanation:
⇒ (3y - 2)² + 7 - 7 = 43 - 7
⇒ (3y - 2)² = 36
⇒ √(3y - 9)² = √36
⇒ 3y - 9 = ±6
⇒ 3y - 9 + 9 = 6 + 9
⇒ 3y = 15
⇒ 3y/3 = 15/3
⇒ y = 5
⇒ 3y - 9 + 9 = -6 + 9
⇒ 3y = 3
⇒ 3y/3 = 3/3
⇒ y = 1
Answer:
4x - 7y = 19
4(-4) - 7(-5) = 19
-16 - (-35) = 19
-16 + 35 = 19
19 = 19
(-4,-5) is a solution to given equation.
4(9) - 7(6) = 19
36 - 42 = 19
-6 ≠ 19
(9,6) is not a solution to given equation.
4(1) - 7(-3) = 19
4 - (-21) = 19
4 + 21 = 19
25 ≠ 19
(1, -3) is not a solution to given equation.
4(-6) - 7(2) = 19
-24 - 14 = 19
-38 ≠ 19
(-6,2) is not a solution to given equation.
