Step 1. Divide both sides by [tex]3[/tex]
[tex]5x+20= \frac{45}{3} [/tex]
Step 2. Simplify [tex] \frac{45}{3} [/tex] to [tex]15[/tex]
[tex]5x+20=15[/tex]
Step 3. Subtract [tex]20[/tex] from both sides
[tex]5x=15-20[/tex]
Step 4. Simplify [tex]15-20[/tex] to [tex]-5[/tex]
[tex]5x=-5[/tex]
Step 5. Divide both sides by [tex]5[/tex]
[tex]x=-1[/tex]
Done! Your answer is [tex]x=-1[/tex]
