What would be the equation of this problem?

If you are talking about a SINGLE mass of 50 kg pulled in opposite directions, determine the net horizontal force. That would be

Fx = -100 cos 120 - 30 -Ff

where Ff is the friction force, whicb is (100 sin 120)* 0.1

I get

Fx = 50 - 30 - 8.67

for the net horizontal force. Divide by the mass to get acceleration.
