Solve the system by substitution 3x+2y+3 y=-2+1?

Question

Be sure to state your solution

Answer 1

c'mon i'm a fifth grader and this is easy...
do you mean 3x+2y=3 ?
ok

y=(-2+1)
y=-1

3x+2(-1)=3
simplify
3x+(-2)=3
subtract -2 from the equation
3x+(-2+2)=3+2
simplify:
3x=5
divide '3' from the equation
x=5/3

SO....

x=5/3
y=-1

Answer 2

3x + 2y + 3y = -2 + 1
3x + 2y + 3y = -1
3x + 5y = -1
so if you substitute you will find that x = -2 and y = 1( I don't know how to do in a different way besides my mind.lol.)
3 (-2) + 5 (1) = -1
-6 + 5 = -1
-1 = -1
(If you do some other crap that people have up there you can't get it right when you check it.... HA!)

Answer 3

the second equation might be
y = -2x +1 . . . . 2nd equation
3x + 2y + 3 . . . . 1st equation
3x (-2x + 1) + 3 . . substitute the 2nd equation to the first
x = 3 - 1
x = 2 . . . . . . substitute this to 2nd equation
y = -2(2 ) +1
y= -3

Answer 4

3x+2y+3y=-2+1
3x+5y=-1
y=-1-3x/5
when x=0;
then y= -1-3(0)/5;
y=-1.

hence get for other values

Answer 5

I think there's a typo in your equations. Shouldn't there be two equations and two equals-signs?

Answer 6

x=0.5 and y=-0.5
