Question

Could somebody show me how to check this equation?
3x – 7 = 5x + 19
5x - 3x = -7 - 19
2x = -26
/2 /2
x = -13

Answer 1

to check if your answer is good
you replace x in the equation be the value you found which is in this case -13
and left must match with right

Answer 2

do you get it?

Answer 3

there is 2 x's so where should i put it?

Answer 4

you have to replace all the x's in the equation be -13

Answer 5

Answer 6

Answer 7

soo 3(-13)-7=5(-13)=19??

Answer 8

Answer 11

Answer 12

just a little correction

Answer 13

Hmmm im sorry I'm still a little confused on how to write it >.<

Answer 14

you wrote it correctly already!
3(-13)-7=5(-13)+9

Answer 15

Ohh LOL >.< sorry. so thats it? no more solving?

Answer 16

if you did calculate left side by itself
and did right side by it self
you should get the same number left and right
that means you equation checks out
