Step-by-step explanation:

Substitute the value of y into the equation;

[tex]8x-2(4)=48[/tex]

Find the value of x.

Multiply;

[tex]8x-8=48[/tex]

Add 8 to each side;

[tex]8x=56[/tex]

Divide each side by 8;

[tex]x=7[/tex]

Answer:

x = 7

Step-by-step explanation:

Given:

  • y = 4

Step-1: Substitute the y-variable in the equation (8x – 2y = 48)

  • ⇒ 8x - 2y = 48
  • ⇒ 8x - 2(4) = 48

Step-2: Simplify the L.H.S

  • ⇒ 8x - 2(4) = 48
  • ⇒ 8x - 8 = 48

Step-3: Add 8 both sides

  • ⇒ 8x - 8 = 48
  • ⇒ 8x - 8 + 8 = 48 + 8
  • ⇒ 8x = 56

Step-4: Divide 8 both sides

  • ⇒ 8x = 56
  • ⇒ 8x/8 = 56/8
  • ⇒ x = 7
