Question

For each equation, determine if there is no solution, one solution, or infinitely many solutions. Then, solve the equations:

-1.7V + 2.8 = 1.4V - 3.15 + 2.8

Answer 1

The equation -1.7V + 2.8 = 1.4V - 3.15 + 2.8 has one solution, which is V = 0.79032258.

Step-by-step explanation:

-1.7V + 2.8 = 1.4V - 3.15 + 2.8

Combine the constants:

-1.7V + 2.8 = 1.4V - 0.35

Group the variables on one side:

-1.7V - 1.4V = -2.8 + 0.35

Add the coefficients:

-3.1V = -2.45

Divide both sides by -3.1:

V = -2.45 / -3.1

Simplify the fraction:

V = 0.79032258

Therefore, the equation has one solution, which is V = 0.79032258.
