Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
<u><em>Solving for X:</em></u>
<u>Multiply Issac's by -1:</u>
y= 1x+ 9
-y=-2x-1
<u>Combine:</u>
0=-x+8
<u>Add x to both sides:</u>
<em><u>x=8</u></em>
<em><u>Solving for Y:</u></em>
<em>Since we already have x, we only need to input the x value into one of the formulas:</em>
y=1(8)+9
<u>Simplify parenthesis with multiplication:</u>
y=8+9
<u>Add:</u>
<u><em>y=17</em></u>
If you feel unsure, check your work with both equations:
(17)=2(8)+1
17=16+1
17=17=Good
(17)=1(8)+9
17=8+9
17=17=Good
Please give a brainliest and a thx ;)
