Answer:
hey! This was the only part of mathematics I ever enjoyed! So consider this both of our lucky days: Answer is : (2,7)
Step-by-step explanation:
basically plug in Y to the first equation as sox + 4(-x + 9) = 30
x - 4x + 36 = 30- 3x = - 6
x = 2
then plug that in to Y!
Y = -(2) + 9
so Y = 7
and our answer is : (2,7)
You would change the whole number to a fraction by putting it over 1 and make the mixed number an improper fraction by multiplying the whole number part of the mixed number by the denominator and then and the numerator
6+1
8-1
10-3
14-7
Theses are also equal to ur answer
