For solving system of equations my problem is:
x-4y=-14
x+5y=13
How do I solve that

The answer is (-2,3)

Step-by-step explanation:

x=-2 and y=3

Step-by-step explanation:

I've already answered this question.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

i think the amount would be $140.62
