Question

Make y the subject:

5x + 2y = 11

Answer 1

5x + 2y = 11

Subtract 5x from both sides:

2y = -5x + 11

Divide both side by 2:

y = -5/2 x + 11/2

Answer: y = -5/2 x + 11/2

Answer 2

Does that mean solve for y? If so, here it is:
5x + 2y = 11.

Move the x term by subtracting.
2y = -5x + 11

Divide by 2.
y = -5/2x + 11/2
