Because 42 doesn't go into 63, you have to go larger. Start by multiplying 63 by 2.
63*2=126
42 goes into 126 3 times even, so the LCM of 42 and 63 is 126 :)
Answer:
41
Step-by-step explanation:
Answer:The answer is 1/2 or you can do 3/6 if it doesnt need to be simplified
Step-by-step explanation:
Answer:
[1] x - 6y = 3
[2] x + 2y = 5
Graphic Representation of the Equations :
-6y + x = 3 2y + x = 5
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -2y + 5
// Plug this in for variable x in equation [1]
[1] (-2y+5) - 6y = 3
[1] - 8y = -2
// Solve equation [1] for the variable y
[1] 8y = 2
[1] y = 1/4
// By now we know this much :
x = -2y+5
y = 1/4
// Use the y value to solve for x
x = -2(1/4)+5 = 9/2
Solution :
{x,y} = {9/2,1/4}
