How do you solve 32 - 6x = 53?

katrin2010 [14]

$\large\boxed{x=-\frac{7}{2}}$

To solve for $x$ , we need to isolate it on one side of the equation.

The most important part of this is knowing that whatever we do to one side of the equation, we must also do to the other.

Subtract 32 from both sides of the equation.

$\begin{aligned}32-32-6x&=53-32\\-6x&=21\end{aligned}$

Divide both sides of the equation by $-6$ .

$\begin{aligned}\frac{-6x}{-6}&=\frac{21}{-6}\\x&=\boxed{-\frac{7}{2}}\end{aligned}$

Step-by-step explanation:

Height of ladder = 12ft .

Here perpendicular is height to which it reaches .

When angle is 30⁰ :-

=> sin 30⁰ = H/12

=> ½ = H/12

=> H = 12/2

=> H = 6m ( ans )

When Angle is 45⁰ :-

=> sin45⁰ = H/12

=> 1/√2 = H/12

=> H = 6*√2*√2/√2

=> H = 6√2 m ( ans )

When angle is 60⁰ :-

=> sin60⁰ = H/12

=> √3/2 = H/12

=> H = 12 *√3/2

=> H = 6√3 ( ans )

hope it helped !
