Question

Does anyone know the answers for these ?

Answer 1

3 = x - 3 + 5x

or, 3 + 3 = x + 5x

or, 6 = 6x

or, 6/6 = x

or, 1 = x

or, x = 1

-117 = -5(8x-8) + 3

or, -117 - 3 = -40x + 40

or, -120 - 40 = -40x

or, -160 = -40x

or, -160/-40 = x

or, 4 = x

or, x = 4

-3 = -4x + 6 - 5x

or, -3 - 6 = -4x - 5x

or, -9 = -9x

or, -9/-9 = x

or, 1 = x

or, x = 1

Answer 2

Answer:

$1)3={\color{#c92786}{x}}-3+{\color{#c92786}{5x}} \\ 3=6−3 \\ 3+3=6−3+3 \\ 6=6 \\ solution - x=1$

$2)-117={\color{#c92786}{-5(8x-8)}}+3 \\ −117=−40+40+3 \\ −117=−40+43 \\ −117−43=−40+43−43 \\ −160=−40 \\ \frac{ - 160}{ - 40} = \frac{ - 40x}{ - 40} \\ Solution - x=4$

$3)-3={\color{#c92786}{-4x}}+6{\color{#c92786}{-5x}} \\ −3=−9+6 \\ −3−6=−9+6−6 \\ −9=−9 \\ \frac{ - 9}{ - 9} = \frac{ - 9x}{ - 9} \\ Solution - x=1$
