Answer:

Let the points for School X be a

and for the School Y be b.

From the given condition : School X has 8 more points than school Y.

we have;

a = b+8                      ......[1]

Also, School X has 3 times as many points as school Y, which implies

a = 3b                       ......[2]

Substitute the value  a of [2] in [1]; to solve for b;

we have;

3b=b+8

Subtract b from both sides of an equation we get;

3b-b=b+8-b

Simplify:

2b=8

Divide by 2 from both sides of an equation we get;

\frac{2b}{2}= \frac{8}{2}

Simplify:

b=4

Substitute the value of b in equation [2];

a=3 \cdot 4 = 12

Therefore, School X has 12 points and School Y has 4 points.

Two numbers have a sum of 24 and 7 times the first number minus the second number is equal to 16. what is the smaller number
Varvara68 [4.7K]
You want the minimum of the solutions to
  x + y = 24
  7x - y = 16

There are many ways to solve these equations. Adding them together, you get
  8x = 40
  x = 5

Since this value is less than 12, it is the smaller number. The smaller number is 5.
