Which Methods Correctly Solve For Variable X In The Equation 34 X 86 class=

Sagot :

SOLUTION

The equation given is

[tex]\frac{3}{4}(x-8)=6[/tex]

Step1

Multiply both sides by

[tex]\frac{4}{3}[/tex]

We have

[tex]\begin{gathered} \frac{4}{3}\times\frac{3}{4}(x-8)=\frac{4}{3}\times6 \\ \\ x-8=8 \end{gathered}[/tex]

Step2

Add 8 to both sides of the equation

[tex]\begin{gathered} x-8+8=8+8_{} \\ x=16 \end{gathered}[/tex]

Therefore, the correct method that solves the equation is

5. Multiply both sides by 4/3 and then add 8 to both sides of the equation

similarly,

Distribute 3/4 to (x-8)

[tex]\begin{gathered} \frac{3}{4}(x-8)=6 \\ \frac{3}{4}x-6=6 \end{gathered}[/tex]

Then add 6 to both sides

[tex]\begin{gathered} \frac{3}{4}x-6=6 \\ \\ \frac{3}{4}x-6+6=6+6 \\ \frac{3}{4}x=12 \end{gathered}[/tex]

Then multiply both sides by 4/3

[tex]\begin{gathered} \frac{3}{4}x\times\frac{4}{3}=12\times\frac{4}{3} \\ \\ x=16 \end{gathered}[/tex]

Hence

2. Distribute 3/4 to (x-8), then add 6 to both sides and finally multiply both sides by 4/3

Therefore

Distribute 3/4 to (x-8), then add 6 to both sides and finally multiply both sides by 4/3
