Option D is the correct answer.
Given equations are:
4x - 2y = 7
3x - 3y = 15
Multiplying 1st equation by 3 and second equation by 4, we get:
12x - 6y = 21
12x - 12y = 60
Now subtracting the equations will eliminate x from the equations, leaving y as the only variable.
4(2y−9) is the correct answer
If you set the two equations equal to each other, then solve for x, and then you substitute your answer into one of the equations you will get your solution. 8x+4=10x-6 4=2x-6 10=2x 5=x 10(5)-6=44 8(5)+4=44 44 IS YOUR ANSWER.
Answer:
1:2
Step-by-step explanation:
You didn't really specify, but I'm going to assume you meant as simplified as possible. If you write it as a fraction, it will be ½ or as a decimal it will be 0.5.
Since 2 is less than or equal to 2, you input it into the first equation!
3•(2) -5
6-5
1
The answer is 1!
