Question

(4x + y = 17
2y + x - 5y +2 = 2 solve by substitution method​

Answer 1

Step-by-step explanation:

4x+y=17. (1)

x-3y=0. (2)

from eq. (1)

y=17-4x. (3)

putting the value of y in eq. (2)

x-3(17-4x)=0

x-51+12x=0

13x=51

x=51/13

x=3.9

putting the value of x in eq. (3)

y=17-4(3.9)

y=17-15.6

y=1.4

Answer 2

Answer

Step-by-step explanation:

eq 1. (4x+y=17)

eq 2. (2y+x-5y+2=2)

or, y=17-4x

Putting the value of y =17-4x in eq.2 we get [ 2*(17-4x)+ +x-5*(17-4x) +2]= 2

[ 34 -8x +x -80+20x +2] = 2

[ 21x -8x -46 +2] = 2

[ 13x - 44 ] = 2

13x = 44 +2

13x = 46

x = 46/13
