Answer:
2.
Step-by-step explanation:
First, you have to multiply the whole equation by the common denominator, which is 35.
-6/5x+1/7=-79/35
35(-6/5x+1/7)=35(-79/35)
-42x+5=-79
-42x=-84
x=2
To check, you can plug this into the original equation.
-6/5(2)+1/7=-79/35
-12/5+1/7=-79/35
35(-12/5+1/7)=35(-79/35)
35(-84/35+5/35)=-79
35(-79/35)=-79
-79=-79
