Answer: The correct option is
(A) -4.
Step-by-step explanation: We are given to find the value of x that makes the following equation true :
![1.4x+2.6x=-16~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9y6qkedxy7pbvbwuagtyu14a8n5vu0dich.png)
To find the value of x, we must solve the given equation.
The solution of equation (i) is as follows :
![1.4x+2.6x=-16\\\\\Rightarrow (1.4+2.6)x=-16\\\\\Rightarrow 4x=-16\\\\\Rightarrow x=-(16)/(4)\\\\\Rightarrow x=-4.](https://img.qammunity.org/2019/formulas/mathematics/middle-school/s99ixsrzm32ymnr6qmaayzm2unqp47g56q.png)
Thus, the required value of x is -4.
Option (A) is CORRECT.
