Question

Simplify: x+1/3 + x+4/5 = x-4/7

Answer 1

$\frac{1}{3} +x+\frac{4}{5} =-\frac{4}{7}$

$x+\frac{17}{15} =-\frac{4}{7}$

$x=-\frac{4}{7} -\frac{17}{15}$

$x=-\frac{179}{105}$

Answer 2

Answer:

×+1/3 + ×+4/5= ×-4/7

(15×-5+15×+12)÷15=(7×-4)÷7

(30×+22)7=105×-60

105×-210×=-60-154

105×=90

21×=18

7×=6

×=6/7
