92 = -4(2r - 5)
r = ?
Help!
2 answers:
First to get rid of the parantheses we must multiply -4 times any number inside of the parantheses.
<em>92=-4(2r-5)</em>
<em>92=-8r+20</em>
Next subtract 20 from both sides
<em>92=-8r+20</em>
<em>72=-8r</em>
Divide both sides by -8
<em>72=-8r</em>
<em>72/-8=-8r/-8</em>
<em>-9=r</em>
<em>Our final answer is -9</em>
