Ab=750 and a=b-5, using this value of a in the original equation gives you:
(b-5)b=750
b^2-5b=750
b^2-5b-750=0
b^2-30b+25b-750=0
b(b-30)+25(b-30)=0
(b+25)(b-30)=0
b=30
Answer:
<u>Undecillion</u> has 36 0's
Let's plug in y=3x-7 into 2x+4y=14
2x+4 (3x-7)=14
Distribute
2x+12x-28=14
Add
14x-28=14
Add 28 to both sides
14x=42
Divide
X=3
Y=3 (3)-7
Y=9-7
Y=2
(3,2) A the solution is (3,2)
