Question

Solve the simultaneous equations.
Please help.

Answer 1

the answer is x= 5 and y = 1.5

Answer 2

• Value of x is 5
• Value of y is 1.5

Explaination :

Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.

• 5x - 4y = 19 (Equation No 1)
• x + 2y = 8 (Equation No 2)

★ From Equation No 2 :-

>> x + 2y = 8

>> x = 8 - 2y

★ In Equation No 1 :-

Substituting here the value of x which we got above as (8 - 2y).

>> 5x - 4y = 19

>> 5 (8 - 2y) - 4y = 19

>> 40 - 10y - 4y = 19

>> 40 - 14y = 19

>> -14y = 19 - 40

>> -14y = -21

>> 14y = 21

>> y = 21 / 14

>> y = 1.5

★ Finding out value of x :-

>> x = 8 - 2y

>> x = 8 - 2 (1.5)

>> x = 8 - 2 × 1.5

>> x = 8 - 3

>> x = 5
