Question

Solve this equation please.... 7x+20+9x-2=180

Answer 1

7x+20+9x-2=180

16x+20-2=180

16x-18=180

+18 to both sides...

16x=198

divide by 16 to both sides...

x=12.375!

Answer 2

Answers: ⇒ $x=\frac{81}{8}$

$7x+20+9x-2=180$

$7x+9x+20-2=180$

$16x+20-2=180$

$16x+18=180$

$16x+18-18=180-18$

$16x=162$

$\frac{16x}{16}= \frac{162}{16}$

$x=\frac{81}{8}$

Hope this helps!
