By the graph, it looks like (3/4, 3.5) but let's solve it:
4x+2y = 10
-2(2x+3y = 12) -->
-4x-6y = -24
+4x+2y = 10
----------------
0 + -4y = -14
-4y = -14
-4y/-4 = -14/-4
y = 7/2 = 3.33
4x+2y = 10
4x+2(7/2) = 10
4x+7 = 10
4x = 3
x = 3/4 = 0.75
So the solution is at (0.75, 3.33)
closest is C) (1, 4)

2/3 + 3/4 + 4/2. If a fraction appears in your answer, it should be in simplified form.

V125BC [204]

We must first make each fraction have a common denominator, this will be 12
2/3 * 4/4 = 8/12
3/4 * 3/3 = 9/12
4/2 * 6/6 = 24/12
we can then add the numerators of each fraction
8 + 9 + 24 = 41
so our answer is 41/12
we can not simplify any further and thus get
41/12
