Full solution

Q. Solve the system of equations.\newline{y=6x+4y=14x4 \left\{\begin{array}{l}y=-6 x+4 \\ y=\frac{1}{4} x-4\end{array}\right.
  1. Set Equations Equal: Set the two equations equal to each other since they both equal yy.6x+4=(14)x4-6x + 4 = (\frac{1}{4})x - 4
  2. Move X Terms: Move all xx terms to one side of the equation by adding 6x6x to both sides.\newline\(-6x + 66x + 44 = \left(\frac{11}{44}\right)x + 66x - 44
  3. Simplify Equation: Simplify the equation. 4=254x44 = \frac{25}{4}x - 4
  4. Move Constant Terms: Move the constant terms to one side by adding 44 to both sides.\newline4+4=(254)x4 + 4 = \left(\frac{25}{4}\right)x
  5. Simplify Constants: Simplify the constant terms. 8=(254)x8 = \left(\frac{25}{4}\right)x
  6. Solve for X: Solve for xx by multiplying both sides by the reciprocal of 254\frac{25}{4}, which is 425\frac{4}{25}.8×425=x8 \times \frac{4}{25} = x
  7. Calculate X Value: Calculate the value of xx.x=3225x = \frac{32}{25}x=1.28x = 1.28
  8. Substitute X Value: Substitute the value of xx back into one of the original equations to solve for yy. We'll use y=6x+4y = -6x + 4.\newliney=6(1.28)+4y = -6(1.28) + 4
  9. Calculate Y Value: Calculate the value of y.\newliney = 7.68+4-7.68 + 4\newliney = 3.68-3.68
