(a+b+c)(a2+b2+c2-ab+bc+ac)-3abc
Answers
Answer:
Solve the following: x – 2= 7
Answer:
Given, x -2 = 7
=> x – 2 + 2= 7 + 2 [Adding 2 both sides]
=> x = 9
Question 2:
Solve of the following: y + 3 = 10
Solution:
Given, y + 3 = 10
=> y + 3 – 3 = 10 – 3 [subtracting 3 on both side]
=> y = 7
Question 3:
Solve the following: 6 = z + 2
Answer:
Given, 6 = 2 + z
=> 6 – 2 = z + 2 – 2 [Subtracting 2 both sides]
=> 4 = z
=> z = 4
Question 4:
Solve the following: 3/7 + x = 17/7
Answer:
Given, 3/7 + x = 17/7
=> 3/7 + x – 3/7 = 17/7 – 3/7 [Subtracting 3/7 on both sides]
=> x = (17 - 3)/7
=> x = 14/7
=> x = 2
Question 5:
Solve the following: 6x = 12
Answer:
Given, 6x = 12
=> 6x/6 = 12/6 [Dividing 6 on both side]
=> x = 2
Question 6:
Solve the following: t/5 = 10
Answer:
Given, t/5 = 10
=> t/5 * 5 = 10 * 5 [Multiply by 5 on both side]
=> t = 50
Question 7:
Solve the following: 2x/3 =
