if 30 girls are added then for 25 days the food will last.
Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)
Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14
Therefore, there is no solution.
Answer:Rearrange the equation by subtracting what is to the right of the greater equal sign from both sides of the inequality :
9*x-4-(95)≥0

Step-by-step explanation:
Hello :
6x+y = 8
y = -6x+8 m= -6(same slope '<span>parallel')
an equation is : y-9 = -6(x-8)</span>
