Question

Find x if : 5(1−x )+3(1+x )=6

Answer 1

Answer:

x=1

Step-by-step explanation:

5(1-x)+3(1+x)=6

5-5x+3+3x=6

8-2x=6

-2x=6-8

-2x= -2

x= -2/-2

x=1

Find $x$ if: $5(1−x)+3(1+x) = 6$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Given⫸}}}}}}$

$5(1−x)+3(1+x) = 6$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷To\:find⫸}}}}}}$

The value of $x.$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Solution⫸}}}}}}$

$5(1−x)+3(1+x) = 6$

Remove the brackets.

$➳\: 5-5x+3+3x = 6$

$➳ \:-2x+8 = 6$

Subtract 8 from both sides.

$➳ \:-2x+8-8 = 6-8$

$➳ \:-2x = -2$

Divide both sides by $(-2).$

$➳ \:{\frac{-2x}{-2}} = {\frac{-2}{-2}}$

$➳ \:x = 1$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Hence⫸}}}}}}$

$x = 1$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Therefore⫸}}}}}}$

The value of $x$ is $1.$

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Verification⫸}}}}}}$

$5(1−x)+3(1+x) = 6$

Substitute $x$ with $1.$

$➳ \:5(1-1)+3(1+1) = 6$

$➳ \:(5×0)+(3×2) = 6$

$➳ \:0+6 = 6$

$➳ \:6 = 6$

So, L.H.S = R.H.S.

Hence, verified.
