Solve the equation. 5/6x - 4 = -2

Agata [3.3K]

Answer:

A

Step-by-step explanation:

Given

$\frac{5}{6}$ x - 4 = - 2 ( add 4 to both sides )

$\frac{5}{6}$ x = 2 ( multiply both sides by 6 to clear the fraction )

5x = 12 ( divide both sides by 5 )

x = $\frac{12}{5}$ = 2 $\frac{2}{5}$ → A

Directions:Solve this equation

avanturin [10]

Answer:

-3.21538461538

Step-by-step explanation:

$\mathrm{Equation\;Given:}\; 5+5x=\frac{12x-\frac{12}{5}\cdot \:7}{5}$

$\mathrm{Multiply\;both\;sides\;by\;5}:$ $5\cdot \:5+5x\cdot \:5=\frac{12x-\frac{12}{5}\cdot \:7}{5}\cdot \:5$

$\mathrm{Now\;we\;have\;}:$ $25+25x=12x-\frac{84}{5}$

$\mathrm{Subtract\;by\;sides\;by\;25}:$ $25+25x-25=12x-\frac{84}{5}-25$

$\mathrm{Thus\;we\;have}:$ $25x=12x-\frac{209}{5}$

$\mathrm{Subtracting\;12x\;from\;both\;sides}:$ $25x-12x=12x-\frac{209}{5}-12x$

$\mathrm{So\;then\;we\;have:}$ $13x=-\frac{209}{5}$

$\mathrm{Now\;divide\;both\;sides\;by\;13}:$ $\frac{13x}{13}=\frac{-\frac{209}{5}}{13}$

$\mathrm{Hence\;we\;have}:\;\;x=-\frac{209}{65}$

$\mathrm{Decimal\;form}:-3.21538461538$
