Answer:
one solution
Step-by-step explanation:
* Lets start to solve the question
- The 1st equation x - y = -4
- The 2nd equation 3x + y = 8
- We will use the elimination method to solve this system of equation
∵ x - y = -4 ⇒ (1)
∵ 3x + y = 8 ⇒ (2)
- Add the two equation (1) and (2) to eliminate y
∴ x + 3x = -4 + 8
∴ 4x = 4
- Divide both sides by 4
∴ x = 1
- Substitute the value of x in equation (1) or equation (2) to find
the value of y
- We will use equation (1)
∴ 1 - y = -4
Subtract 1 from both sides
∴ -y = -5
- Divide both sides by -1
∴ y = 5
∴ The solution is (1 , 5)
* The system has one solution
Answer:
9 5/7
Step-by-step explanation:
You add all the 13/14 then divided it by 14
Then add all the while numbers then add then add them all together
Answer:
the value of x = 56
Step-by-step explanation:
if both are similar figures, then ratio of their
sides will be constant , so
=》14 / 17 = x / 68
=》14 / 17 × 68 = x
=》14 × 4 = x
=》x = 56
hence, value of x = 56.
i hope you got it.
