-Its simple just plug it in. 2(-5)=-10 + 3(11) which = 23, and then the other way it is 7. So yes, yes it is right-2x + 3y = 233x + 2y = 76x + 9y = 696x + 4y = 145y = 55y = 11x = -5You certainly gotthe right answer.-You got the right answer.......
So, plug -5 for x in 2x+3y=23 and 11 for y ==> 2(-5)+3(11) = 23 ==> -10+33 = 23 ==> 23=23.
Do the same for 3x+2y = 7 ==> 3(-5)+2(11) = 7 ==> -15+22 = 7 ==> 7=7
You did it right! :D
You are right. I will use elimination.
4x + 6y = 46
9x + 6y = 21
Subtract the second equation from the first.
4x - 9x = 46 - 21
-5x = 25
x = -5
Substitute.
2(-5) + 3y = 23
-10 + 3y = 23
3y = 33
y = 11
You know that you can check your answer without reworking the problem.
Just substitute -5 for x and 11 for y in each equation and see if the
equations speak the truth.
I'ts simple just plug it in. 2(-5)=-10 + 3(11) which = 23, and then the other way it is 7. So yes, yes it is right
You got the right answer.
