Solve the system of linear equations by substitution. x=2y+7
3x−2y=3
solution: (
,
)

Y=-4.5 and x=-2
So your first “equation equals to x so then you substitute the X in the second equation with the first equation. Which would give you 3(2y+7)-2y=3 then you solve (make sure to distribute). Which would give you y=-4.5 Can you substitute your y answer in your first equation. Which would be x= 2(-4.5)+7 then your solve

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !
