Question

S is the midpoint of stack R T with bar on top. If RS = 7x - 3 and ST = 3x + 1, then what is the value of x?

Answer 1

The value of x is 1.

Explanation:

Given that S is the midpoint of RT so we can assume that RS is equal to ST. Next, we have to compare it :

`RS = ST`

`7x - 3 = 3x + 1`

`7x - 3x = 1 + 3`

`4x = 4`

`x = 1`
