As far as can see there are 2 correct methods shown, although there are other more efficient ways to solve this.
The 2 correct methods shown are:

and

The reason for this is because if we want to solve for "x", we must first isolate it. Normally we would isolate the "y variable", but because there is none in this equation we have to automatically assume that the "y" value has been given to us.
If you would like to see the math behind these 2 solutions I'll be more than happy to add it, if I can still edit my answer at that point in time. Also if you find out that this answer is wrong please tell me in the comments below, and I promise that I will come back and rework my math. Thanks!
Answer:
C (1, 4), because both lines pass through this point
Step-by-step explanation:
do the graph when both lines pass through the same point
1) Line M, for: x=0, and y=0
2) Line N, for: x=0, and y=0
Answer: a square is both rectangle and quadrilateral.a trapezoid, rhombus and parallelogram is a quadrilateral. A parallelogram is also a rectangl.
Step-by-step explanation:
Answer: 360
<u>Step-by-step explanation:</u>
LCM is least common multiple. In other words, what number is divisible by 24, 36, and 60?
Factor each term. See what they have in common and then multiply the common term by all of the leftovers.
24 36 60
∧ ∧ ∧
12 2 12 3 12 5
They all have a 12 in common. The leftovers are 2, 3, & 5.
So, the LCM is 12 × 2 × 3 × 5 = 360
