Question

What value of x makes the equation true?

1.4x+2.6x=−16




x=−4

x=−13

x=−19

x=−48

Answer 1

`1.4x + 2.6x = - 16 \\ 4x = - 16 \\ x = ( - 16)/(4) \\ x = - 4 \\ thank \: you`

Answer 2

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
