Answer:
Step-by-step explanation:
L1 -x + 2y = -1
L2 5x - 10y = 6
-x + 2y = - 1 multiply by -1
x - 2y = 1 multiply by 5
5x - 10y = 5 is similar that 5x - 10y = 6
The system has no solution
The answer is b I believe but ion really know good luck
Answer: X - 6
If you were to write an equation you can use Y to represent Joshua's age, X - 6 = Y
Y=3x+2 when x=-3
=> y= 3(-3)+2 = -9+2 =-7
