Calculating Vector C's X Component | Vector x Components Help

[the_d]

I have a question. Vector A has x and y components of -20cm and 15 cm, respectively; vector B has x and y components of 10.9cm and -20 cm, respectively. If A - B + 3C = 0, what is the x component of C?

I found out that C = -0.73 cm but that's not what the question is asking.

Use the "x" and "y" components of A, B, and C and solve for the required quantities:

A_x - B_x + 3C_x = 0
A_y - B_y + 3C_y = 0
