Answer is -7x+4y-z

so u have to basically only add or subtract the numbers with the same letter on the end so -4x - 3x = -7x and 2y+2y = 4y and -2z +z = -z

Hope this helps
Remember to always put the same variable together. If the variable stands alone without a number it always means (1). Hope this helps!
