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.

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

Step-by-step 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

yes

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
