"x"/"7x - 3"x7x - 3 + "x + 2"/"15x + 30" = "22x - 3"/"105x - 45"x + 215x + 30=22x - 3105x - 45

Explanation:

"x"/"7x - 3" +" x + 2"/"15x + 30"x7x - 3+ x + 215x + 30

"x"/"7x - 3" +" x + 2"/"15(x + 2)"x7x - 3+ x + 215(x + 2)

"x"/"7x - 3" +"1"/"15"x7x - 3+115

"15x + 7x - 3"/"(7x - 3)(15)"15x + 7x - 3(7x - 3)(15)

"22x - 3"/"(7x)(15) - (3)(15)"22x - 3(7x)(15) - (3)(15)

"22x - 3"/"105x - 45"22x - 3105x - 45
