Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
Solving for X:
Multiply Issac's by -1:
y= 1x+ 9
-y=-2x-1
Combine:
0=-x+8
Add x to both sides:
x=8
Solving for Y:
Since we already have x, we only need to input the x value into one of the formulas:
y=1(8)+9
Simplify parenthesis with multiplication:
y=8+9
Add:
y=17
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 ;)
