Question

how do you solve x − 3y = 7
4x + 2y = 14

Answer 1

x-3y=7 and 4x+2y=14

x=7+3y

using substitution method.

substitude x=7+3y in 4x+2y+=14

4(7+3y)+2y=14

28+12y+2y=14

28+14y=14

14y=14-28

14y=-14

y=-14÷14

y=-1

x=7+3y

x=7+3(-1)

x=7-3

x=4

ans. the solution to this system of linear equation is (4,-1)
