Answer:
(~1.6,~-8.6)/(1.599,-8.597)
Explanation:
This uses the system of equations, if you'd like to find more examples. First, let's mess with the first equation and solve for the easiest findable variable.
1. 3x+8y = -13 -> x = (-13-8y)/3 & y = (-13-3x)/8
2. Using the x equation because it's easier to use when entering into the second equation, we can get 14(-13-8y/3)
(-182-112y)/3 = -10 = 3y/5 is then our new eqn,
Then, we can make the fractions on the right and left equal and find y
9y/15 = -910-560y/15 ->
9y = -910-560y
569y = -910
y = 1.599
3. Now, insert 1.599 into the first x equation we made, x = (-13-8y)/3
to get x = -8.597
4. Your solution is 1.599, -8.597 or ~1.6,~-8.6
