Question

A system of linear equations is shown below.

2x – 3y = 15 -2x + y = -1
Choose a method (Elimination or Substitution) to solve the system of equations. Solve and explain your process.

Answer 1

(x , y) = (1/22 , 4/11)

Explanation:

{2x - 3y = -1

{15x (-2x) + y = -1 you write as a system of equations and then you simplify the expression which would be

{2x - 3y = -1

{- 30x + y = -1 and then you multiple both sides by 15 30x - 45y = 15 { -30x +y = -1 then you divide noth sides of the equation and then you substitute the vaul of y then you solve the equation check the solution nd then get your answer
