Slove algebraically

3x - 4y = -24
x +4y=8

Solve algebrically 3x - 4y = -24 and x + 4y = 8 is x = -4 and y = 3

Solution:

We have been given two equations which are as follows:

3x - 4y = -24   eqn 1

x + 4y = 8   eqn 2              

We have been asked to solve the equations which means we have to find the value of ‘x’ and ‘y’.

We rearrange eqn 2 as follows:

x + 4y = 8

x = 8 - 4y  eqn 3

Now we substitute eqn 3 in eqn 1 as follows:

3(8 - 4y) -4y = -24

24 - 12y - 4y = -24

-16y = -48

y = 3

Substitute "y" value in eqn 3. Therefore the value of ‘x’ becomes:

x = 8 - 4(3)

x = 8 - 12  = -4

Hence on solving both the given equations we get the value of x and y as -4 and 3 respectively.
