Solving Systems by Substitution Day 11. 2x-3y=60 y=2x-5Word bank: (5,-2) (5,5) (2,6) NO SOLUTION INFINITE SOLUTIONS (11, 13) (-2,-6) (0,0) (2.-6) (6,2)

Answer 1

`\begin{gathered} 2x-3y=60\ldots(1) \\ y=2x-5\ldots\text{.}(2) \\ \text{Substitute the value of y in the equation (1).} \\ 2x-3(2x-5)=60 \\ 2x-6x+15=60 \\ -4x=45 \\ x=-(45)/(4) \\ \text{Substitute the value of x in the equation (2).} \\ y=2*-(45)/(4)-5 \\ y=-(45)/(2)-5 \\ y=-(55)/(2) \end{gathered}`
