Question

solve the following pair of linear equations by any suitable method 5 x + 4 Y - 4 is equal to zero x minus 12 minus 20 is equal to zero​

Answer 1

The values of x and y to the given linear equations are x=32 and y=-39

The solution is  (32,-39)

Step-by-step explanation:

Given equations are 5x+4y-4=0 _____ (1) and x-12-20=0

x-12-20=0

x-32=0

Therefore x=32

Solving the given equations by substitution method

Substitute x=32 in equation (1) we have

5(32)+4y-4=0

160+4y-4=0

156+4y=0

156+4y-156=0-156

4y=-156

$y=-\frac{156}{4}$

Therefore y=-39

The values of x and y are x=32 and y=-39

The solution is  (32,-39)
