Answer:

A.) x = -4

Explanation:

1. Simplify the expression

1.4x + 2.6x = -16

Simplify the arithmetic:

4x = -16

2. Isolate the x

4x = -16

Divide both sides by 4:


(4x)/(4) =
(-16)/(4)

Simplify the fraction:

x =
(-16)/(4)

Find the greatest common factor of the numerator and denominator:

x =
(-4 * 4)/(1 * 4)

Factor out and cancel the greatest common factor:

x = -4

A.) x = -4
