Answer:
y = 3 -x
Step-by-step explanation:
Subtract x from both sides of the equation.
x -x +y = 3 -x
y = 3 - x
Since both terms are perfect squares factor the denominator:
answer is <span>C. m²/(m + n)(m - n)</span>
Since they are vertical they are equal to each other.
3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x
So the value of x is 3.25.
Hope this helps :)
