Answer:

Explanation:

Given 4x + 6y - 10x + 13y = 11

If (1, 1) is a solution, then substituting x = 1 and y = 1 into the left hand side of the equation gives 11.

Doing this, we have:

4(1) + 6(1) - 10(1) + 13(1)

= 4 + 6 - 10 + 13

= 13

Proportionally? Not sure. But here is a way to find out the value of x

50° + 2x+40 +4x+8 = 180°
Combine like terms
50°+ 6x + 48=180
(now subtract 50° from both sides)
6x + 48 = 130°
(now subtract 48 from both sides
6x=82°
x= 13.6666667° (repeating decimal)
