How do I calculate surface charge density of sheet on y axis?

Does it not cancel anyhow?

Homework Statement An infinite sheet of charge with a surface charge density of +7.8 micro-Coulomb/m2 lies on x-axis (technically in x-z plane). Another infinite sheet of charge with an unknown charge density lies on y-axis (technically in y-z plane). A positive point charge is placed in first...
