Answer 2

There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have a linear equation in one-variable:

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

0.75(x + 40) = 0.7(x + 20)

75(x + 40) = 70(x + 20)

75x = 70x - 1600

x = -370

Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.
