Question

If(3x+y,5)=(4,x+1)find xand y

Answer 1

3x+y=4
x+1=5
x=5-1
x=4 putting value of x in first equation 3x+y=4
3(4)+y=4
12+y=4
12-4=-y
Y=-8

Answer 2

Answer:

The value of x and y is

x=4 and y= -8

Step-by-step explanation:

The equation given in the question is

(3x+y, 5) = (4, x+1)

we can simplify the equation and write it as

3x+y=4 ----------- eq. ( i)

x+1=5 --------------eq. (ii)

Now it is been simplified into two linear equations

Now to find the values of x and y we just use the substitution method.

from equation (ii)

x+1=5

x=5-1

x=4

Now put the value of x in equation (i) we get

3x+y=

3(4) +y=4

12+y=44

y=12-4

y= -8

so therefore the values of x and y are

x = 4 and y = -8 .
