Question

During the​ women's basketball championship​ game, team a scored 4 more points than team

b.​ together, both teams scored a total of 154 points. how many points did the champion team a score during this​ game?

Answer 1

Sum and difference problem.
Larger number (team a) = (sum+difference)/2 = (154+4)/2 =79
Smaller number (team b)=(sum-difference)/2 = (154-4)/2 = 75

Answer 2

Let

x--------> number of points scored by the team a

y--------> number of points scored by the team b

we know that

`x+y=154` ---------> equation
`1`

`x=y+4` ---------> equation
`2`

substitute the equation
`2` in the equation
`1`

`(y+4)+y=154`

Combine like terms

`y+y=154-4`

`2y=150`

`y=150/2`

`y=75\ points`

Find the value of x

`x=y+4`

`x=75+4`

`x=79\ points`

therefore

the answer is

The number of points scored by the team a was
`79\ points`
