Find the common ratio. (The number you multiply or divide.) 3. Create a recursive formula<span> by stating the first term, and then stating the </span>formula<span> to be the common ratio times the previous term.</span>
What is the question asking
first one is 1 the bottom is 10 2 in 20 3 in 30 4 in 40 5 in 50 6 in 60 7 in 70 8 in 80 9 in 90 then 100
First, isolate y in 7x-y=29 because 1 is y's coefficient.
7x-y=29
-y=29-7x
y=7x-29
Now, substitute 7x-29 for y in 7x+8y=20.
7x+8y=20
7x+8(7x-29)=20
7x+56x-232=20
Add all coefficients.
63x-232=20
Isolate x by adding 232 to both sides.
63x-232=20
63x=252
x=4
Now, substitute 4 for x in your first equation.
y=7x-29
y=7(4)-29
y=28-29
y=-1
Your answer would be (4,-1).

Answer:
Step-by-step explanation:
5 + 5
- 2x = 3 - 4
use your algebra skillz :P to move terms back and forth across the equal sign
5 - 3 - 2x + 5 +4 = 0
2 -2x +9 = 0
