Question

If you can't help me with the solution can someone at least tell me which equation solving method am i supposed to use?

Answer 1

Simplifying
10y + 4 = 2x

Reorder the terms:
4 + 10y = 2x

Solving
4 + 10y = 2x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + 10y = -4 + 2x

Combine like terms: 4 + -4 = 0
0 + 10y = -4 + 2x
10y = -4 + 2x

Divide each side by '10'.
y = -0.4 + 0.2x

Simplifying
y = -0.4 + 0.2x
