    4y = 2x - 10
    Make X the subject of the formula
    Add 10 to both sides
    4y  + 10 = 2x
    divide by 2 in both sides

     \frac{4y + 10}{2}  =  x
    So X =( 4y +10 )÷2

    They are saying that y=6
    Now substitute the equation given with the values

    x =  \frac{(4 \times 6) + 10}{2}
    x =  \frac{24 + 10}{2}
     x = \frac{34}{2}
    x = 17
    Here you go
