Solve for v. –5v = 280 v =

v = -280/5 = -56

Solve for c.

c + 1 = 7.8

c =

c = 7.8 - 1 = 6.8

Solve for y. y/2 = 1.67 y =

To solve for y, we need to isolate it on one side of the equation by multiplying both sides by 2:

(y/2) * 2 = 1.67 * 2

This simplifies to:

y = 3.34

Solve for y.

2y − 4 = 4

y =

To solve for y, we need to isolate it on one side of the equation by adding 4 to both sides:

2y - 4 + 4 = 4 + 4

This simplifies to:

2y = 8

Next, we divide both sides by 2 to solve for y:

(2y)/2 = 8/2

This simplifies to:

y = 4
