Question

What is the solution to this question?

Answer 1

x = -3/5

Explanation:

Given the equation:

`\displaystyle{8x+9=3x+6}`

Solve for the variable x by isolating x-term, first move subtract both sides by 3x:

`\displaystyle{8x+9-3x=3x+6-3x}\\\\\displaystyle{5x+9=6}`

Subtract both sides by 9:

`\displaystyle{5x+9-9=6-9}\\\\\displaystyle{5x=-3}`

Divide both sides by 5:

`\displaystyle{(5x)/(5)=(-3)/(5)}\\\\\displaystyle{x=-(3)/(5)}`

Therefore x = - 3/5

Answer 2

x = -3/5 (or) x = -0.6

Explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 8x + 9 = 3x + 6

Then the value of x will be,

→ 8x + 9 = 3x + 6

→ 8x - 3x = 6 - 9

→ 5x = -3

→ x = -3 ÷ 5

→ [ x = -3/5 ]

Hence, the answer is -3/5.
