Full solution

Q. Solve using elimination.\newline2x5y=15-2x - 5y = 15\newline2x3y=1-2x - 3y = 1\newline(_____, _____)
  1. Write Equations: Write down the system of equations.\newline2x5y=15-2x - 5y = 15\newline2x3y=1-2x - 3y = 1
  2. Eliminate xx: Since the coefficients of xx in both equations are the same but with opposite signs, we can eliminate the xx variable by subtracting the second equation from the first.\newline(2x5y)(2x3y)=151(–2x − 5y) − (–2x − 3y) = 15 − 1
  3. Subtract Equations: Perform the subtraction to eliminate the xx variable.2x+2x5y+3y=151\,-2x + 2x - 5y + 3y = 15 - 1
  4. Simplify Result: Simplify the resulting equation.\newline0x2y=140x - 2y = 14
  5. Solve for y: Solve for y.\newline2y=14-2y = 14\newliney=14(2)y = \frac{14}{(-2)}\newliney=7y = -7
  6. Substitute and Solve: Substitute the value of yy back into one of the original equations to solve for xx. We can use the second equation for this purpose.\newline2x3(7)=1-2x - 3(-7) = 1
  7. Final Solution: Simplify the equation and solve for xx.\newline2x+21=1–2x + 21 = 1\newline2x=121–2x = 1 − 21\newline2x=20–2x = −20\newlinex=20/(2)x = −20 / (−2)\newlinex=10x = 10
