Answer:
x = 2 and y = 3
Step-by-step explanation:
given:
- 2x - 3y = -5
- 2x + y = 7
using elimination rule:
2x - 3y = -5
- 2x - y = - 7
................................
-4y = -12
y = 3
Find x:
2x - 3y = -5
2x - 3(3) = -5
2x - 9 = -5
2x = - 5+9
2x = 4
x = 2
Answer:
[tex]y=3\\x=2\\[/tex]
Step-by-step explanation:
[tex](2x-3y)-(2x+7)\\=-4y=(-5)-(7)\\-4y=-12\\y=12/4\\y=3[/tex]
Insert y=3 into any one equation in the system of equations:
[tex]2x-3(3)=-5\\2x-9=-5\\2x=4\\x=4/2\\x=2[/tex]
or
[tex]2x+(3)=7\\2x=4\\x=4/2\\x=2[/tex]
