Answer:
Step-by-step explanation: so you can only add x’s to x’s and y’s to y’s And so on and so forth so you would do 4y+6y= 10y (keep the variable) then 8x + 4x = 12x and then 7+6+25= 38. In conclusion it would be 10y + 12x +38 (if they don’t have the same variable you can’t add them) hope that helps x
