5x-y10 We're basically just multiplying the 5 by x and the y by 5 and -2.
(5/x= 5x) + (y/-2/-5)
If you want integer coefficients only, multiply the equation of the line by 10. I'm assuming you accidentally left off the "= 0" at the end: -1.7x + 8.5 = 0.
If that's the case, then multiplying the whole equation by 10 results in -17x + 85 = 0.
Here you have only integer coefficients.
Answer:
x = 30
Step-by-step explanation:
In order for the lines to be parallel,
2x + 20 = 80
2x = 60
x = 30
3(4x - 3) - 7x = 5x - 9
First, expand your equation so it will be easier to simplify.
Second, multiply (3)(4x) to get 12x.
Third, multiply (3)(-3) to get -9.
Fourth, combine the like terms. (x and -9 alone).
Fifth, subtract (12x + -7x) to get 5x.
Sixth, change 5x + -9 into a subtraction.
Seventh, since both sides are equal, that means that the equation has infinite solutions.
Answer:
B) infinite solutions
