Who's Weggy?

2x + 3y = 40

-2x + 2y = 20

These are set up so we can just add them for the solution:

5y = 60

y = 12

2y-20=2x

x=y-10=2

Answer: x=2, y=12

Answer:

x = 3

Step-by-step explanation:

$In\: \triangle PQT,\: \overline{PQ}|| \overline {RS}...(Given)\\\\\implies\frac{PS}{ST}=\frac{QR}{RT}\\(By\: Proportionality\: Theorem) \\ \\\implies\frac{2x+4}{5}=\frac{3x+5}{7}\\\\ \implies \: 7(2x + 4) = 5(3x + 5) \\ \\ \implies \:14x + 28 = 15x + 25 \\ \\ 14x - 15x = 25 - 28 \\ \\ - x = - 3 \\ \\ x = 3$
