Answer:
... ................................
See the graph in the attached image.
Step-by-step explanation:
<u>9x</u>-10=<u>5x</u>+14
<u>9x-5x</u>=14+10
4×=24 /:4
<em><u>x</u></em><em><u>=</u></em><em><u>6</u></em>
How do we check that?
9x-10=5x+14
(9×6)-10=(5×6)+14
54-10=30+14
<u>44=44</u>
<u>L</u><u>=</u><u>R</u>
