Question

1.Find the value of x for this simultaneous linear equations.

5x + 2y =31
-2x + 7y = 11

2.Find the value of y for this simultaneous linear equations.

5x + 2y =31
-2x + 7y = 11

Answer 1

Answer:

the value of x for the simulator Arena equation

Answer 2

Answer:

Hey buddy your answer is given below ;).

Step-by-step explanation:

Let's solve it :).

x = 5

y = 3

1. a) 5x + 2y = 31

First,

5x=31-2y

Then,

x=31-2y/5

x = 3

b) -2x + 7y = 11

By putting x in the second equation.

We get,

First,

3*31-2y/5=36-7y

Then,

93-6y/5=36-7y

Then,

93-6y=5(36-7y)

After that,

93-6y=180-35y

Then,

-6y+35y=180-93

Then,

29y=87

Hence,

y=3

Hope it helps you :).
