To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before ad
ding the equations together?
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
1 answer:
Answer:
Multiply both sides of the first equation by 2.
Multiply both sides of the second equation by 3.
Step-by-step explanation:
The y terms are
-3y
2y
The LCM of 2 and 3 is 6.
We need the y terms to add to zero.
Multiply both sides of the first equation by 2 to get -6y.
Multiply both sides of the second equation by 3 to get 6y.
Then -6y + 6y = 0 eliminating the y terms after adding the equations.

Answer:
82.35%
Step-by-step explanation:
60 divided by 340=0.17647058823
Multiply that by 100 and you get 17.647058823
Next, round and you get 17.65
100-17.65=82.35
