5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
Answer:
Gcf or Lcf, you didint state on question
Answer:
Measurements were needed for multiple things, such as agriculture, construction, and trade. Also, many areas developed their own systems for measuring objects making it difficult as people from different places had different results. Eventually, the same system was adopted by the majority of people.
Step-by-step explanation:
Answer:
Point form : (9/5 , -16/5)
Equation form : x=9/5 , y=-16/5
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
