Answer:
Step-by-step explanation:
2p-3q=4
or p=4+3q/2
now putting the value in the second eq we get
3 x(4+3q/2)+2q=9
or 12+9q /2 +2q=9
or 12+9q+4q=18
or 13q=18-12
or q= 6/13
so p will be 4+18/13=70/13 divided by 2 so p=35/13
Answer: the x coordinate of the solution is 1
Step-by-step explanation:
y = x^2 + 1 - - - - - - 1
y – 1 = x - - - - -2
From equation 2 , y = x + 1
Substituting y = x + 1 into equation 1, it becomes
x + 1 = x^2 + 1
x^2 + 1 - x - 1 = 0
x^2 - x - 1 + 1 = 0
x^2 - x = 0
Let x be on the right hand side of the equation and x^2 remains on the left hand side of the equation. It becomes
x^2 = x
Dividing the left hand side of the equation and the right hand side of the equation by x, it becomes
x^2/x = x/x
x = 1
Therefore, x = 1
Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100
