Question

Does anyone know this?

Answer 1

`\sf\\\textsf{For this, we are going to make the graph of these equations. The point where }\\\textsf{these lines intersect is the solution.}\\y=x-1.....(1)\\\textsf{Put x = 1, y = 0.}\\\textsf{Put x = 0, y = -1.}\\\textsf{So the equation (1) passes through (1,0) and (0,-1).}`

`\textsf{We have another equation: }\\\sf\\y=-(3)/(5)x+7.......(2)\\\\\textsf{Put }x=5,\ y=4\\\textsf{Put }x=10, y = 1`

`\textsf{So the equation (2) passes through (5,4) and (10,1).}`

`\sf\\\textsf{Equations (1) and (2) intersect at (5,4). }\\\therefore\ x=5\ and\ y=4`
