Answer:

<em>x ≈ 6.5 , y ≈ 12.1</em>

Step-by-step explanation:

(2x)² + (10.2)² = (16.5)²

4x² = 272.25 - 104.04

x² = 168.21 ÷ 4

<em>x</em> = √(42.0525) ≈ <em>6.5</em>

y² = 42.0525 + 104.04 = 146.0925

<em>y</em> = √(146.0925) ≈ <em>12.1</em>

What is the value of x in the equation. 8 x - 2 y= 48 when y =4​
goldfiish [28.3K]

\qquad❄️\boxed{\bf x = 7}\\\\

We are given –

\qquad \twoheadrightarrow\bf 8x -2 y =48

  • And also value of y's given. So, just put the value of y in the given equation.

___________________________________

\qquad \purple{\twoheadrightarrow\bf 8x -2 y =48}

\qquad \twoheadrightarrow\sf  8x - \underbrace{2 \times 4} =48

\qquad \twoheadrightarrow\sf  8x - 8 =48

\qquad \twoheadrightarrow\sf  8x = 48 +8

\qquad \twoheadrightarrow\sf  8x = 56

\qquad \twoheadrightarrow\sf  x =\cancel{\dfrac{56}{8}}

\qquad \purple{\twoheadrightarrow\bf x= 7}

  • Henceforth, value of x is 7.
