Find the solution to the system of equations, x + 3y = 7 and 2x + 4y = 8. 1. Isolate x in the first equation: x = 7 − 3y 2. Substitute the value for x into the second equation: 2(7 − 3y) + 4y = 8 3. Solve for y: 14 − 6y + 4y = 8 14 − 2y = 8 −2y = −6 y = 3 4. Substitute y into either original equation: x = 7 − 3(3) 5. Write the solution as an ordered pair: ( , )

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !

4, -4 is the other point it would pass through
