The solution of the system of the equation is (2 , -3) ⇒ 2nd answer
Step-by-step explanation:
The steps of the linear combination method are:
- Make the coefficients of one variable in the two equations same in values and different in signs
- Add the two equations to eliminate that variable and make one equation of the other variable
- Solve the equation to find the other variable
- Substitute its value in any one of the two equations to find the variable that eliminate before
∵ The system of equation is:
4x + y = 5 ⇒ (1)
3x + y = 3 ⇒ (2)
Multiply equation (2) by -1 to make y equal in values and different in signs
∵ -3x - y = - 3 ⇒ (3)
- Add equations (1) and (3) to eliminate y
∴ x = 2
- Substitute the value of x in equation (1) or to to find the value of y
∵ 4(2) + y = 5
∴ 8 + y = 5
- Subtract 8 from both sides
∴ y = -3
∴ The solution of the system of equations is (2 , -3)
The solution of the system of the equation is (2 , -3)

It would be the last answer, you can't simplify
Answer:
The Cardboard dimensions are 13cm in length and 12cm in breadth
Step-by-step explanation:
We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)
