Hi!
<h3>We need to isolate b on one side. </h3>
<em>Multiply by 4 on both sides. </em>
-83 * 4 = b/4 * 4
<u>-332 = b</u>
<h2>The answer is b = -332</h2>
<em>To check your answer, put in the value of b. </em>
-83 = -332/4
-83 = -83
<u>This equation is correct. </u>
Hope this helps! :)

Subsitution
2y-x=5
minus 2y both sides
-x=5-2y
times -2 both sides
x=2y-5
subsitute 2y-5 for x in other equation
(2y-5)²+y²-25=0
expand
4y²-20y+25+y²-25=0
5y²-20y=0
factor
5y(y-4)=0
set to zero
5y=0
y=0
y-4=0
y=4
subsitute back
for y=0
x=2y-5
x=2(0)-5
x=-5
one solution is (-5,0)
for x=4
x=2y-5
x=2(4)-5
x=8-5
x=3
one solution is (3,4)
the 2 soltuions are (-5,0) and (3,4)
