-5x +7 = Y
Step-by-step explanation:
3x - y = 8x - 7
<=>3x - 8x = y - 7
<=>-5x = y - 7
<=>-5x + 7 = Y

For this case we have the following equation:
We must solve the equation by following the steps below:
We subtract 1 from both sides of the equation:
On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:
We add x to both sides of the equation:
We divide between 4 on both sides of the equation:
Thus, the correct option is option B
Answer:
Option B
Hi!
We can set up a proportion then cross multiply to solve this.
45 x 100 = 4500
4500/18 = 250
The answer is 250
Hope this helps! :)

Synthetic division is used since the equation is of the third degree. The divisors of -3 are 1, -1, 3, +3. So:
| 2 -7 8 -3
<u>1 | 2 -5 3</u>
| 2 -5 3 0
<u> 1 | 2 -3 </u>
2 -3 0
So the factorization is (x-1)² (2x-3)=0. So:
Synthetic division is used since the equation is of the third degree. The divisors of -4 are 1, -1, 2, -2, 4, -4. So:
| 1 -1 0 -4
<u>2 | 2 2 </u>
1 2 2 0
So the factorization is (x-2)(x²+x+2)=0 . When calculating the discriminant of the trinomial, it is concluded that it has no roots since the result is negative. So you only have one solution.
Synthetic division is used since the equation is of the third degree. The divisors of 2 are 1, -1, 2, -2. So:
| 6 7 9 2
<u>-2 | -12 10 -2</u>
6 -5 1 0
So the factorization is (x+2)(6x²-5x+1)=0 . The quadratic equation is solved by the general formula:
