Question

Solving the equation we get the value 1 point
of y = 1. What will be the next step.
1)--Substituting y = 1 in equation (i), we get, x =
10 - 7(1) = 10 - 7 = 3
2)--Substituting y = 1 in equation (ii), we get, X
=
= 7 + 2(1) = 9
3)--Substituting y = 1 in equation (ii), we get, x
= 3(1) + 7 = 10​

Answer 1

Answer:

For such a simple system, you can use substitution:

x=y+1

from the second equation. Substitute this value of x

in the first equation to the effect that

3(y+1)+4y=10 . this simplifies to 7y=7 , that is y=1 .

Substitute back in the second equation to get

x=y+1=1+1=2 .
