Question

What is the value of x in the following system: y=2x+5
y=-3x+10

Answer 1

ok.... since both equations start off as "y=..." set them equal to each other....

Answer 2

what do you mean equal to each other?

Answer 3

2x+5 = -3x+10

Answer 4

OHHHHH!! OK I got x=-3

Answer 5

no... try again.... be careful...

Answer 6

x=3

Answer 7

how did u get that? try again...

Answer 8

okay so i got 2x+15=-3x and then i subtracter -2 from -3 on the other side

Answer 9

ok... you moved the 10 over from the right side so that means you needed to SUBTRACT 10 from both sides... that 15 should be a -5... ????

Answer 10

OHHHHH! SORRY!! I forgot to do inverse operation !

Answer 11

so let's take it from there now....
2x - 5 = -3x

what next?

Answer 12

you subtract -2 from -3x

Answer 13

you mean subtract 2x from both sides.... ???

2x - 5 -2x = -3x -2x

Answer 14

can you simplify both sides??
