I need Help! I have 2 questions.

⇒ 2nd answer

⇒ 1st answer

Step-by-step explanation:

To solve any equation for one of its variable do that:

∵

→ Multiply both sides by g to take g to the right side

∴

∴ 2m + b = kg

→ Divide both sides by k, to move k to the left side

∵

∴

→ Switch the two sides

∴

∵ ax + bx = c

→ Take x as a common factor from the both terms on the left side

∴ x(a + b) = c

→ Divide both sides by (a + b) to move it to the right sides

∴

∴

b
