Answer:

Okay, so. What I'd do is this.

$(5x+3)+(x+3)=180$

Then I'd combine like terms.

So:

$(5x+3)+(x+3)=180\\ 6x+6=180$

Once you've got 6x, you subtract 6 from 180.

$(5x+3)+(x+3)=180\\ 6x+6=180\\6x=174$

Now all that's left to do is divide each side by 6 to get x.

X should be 29.

Step-by-step explanation:

$(5x+3)+(x+3)=180$

You know that adding the equations will give you 180 because you know they're supplementary.
