5x+4y=-2

3x+4y=10


Make one with negative coefficient to find first what is x then solve for y .


-1(5x+4y)= -1 (-2)

3x+4y=10


-5x-4y=2

+ 3x+4y=10

_________

-x = 12


Divide both sides by -2

-2x/-2=12/-2


X= -6


Now substitute your x into one of the equations to find y .


-5x-4y=2

-5(-6)+4y=2


30+4y=2


Subtract 30 both sides


-4y= 2-30


Divide both sides by -4


Y= -28/-4


Y= 7



Your answer is in point form (-6,7) meaning x is -6 and y is 7.

Amiraneli [1.4K]

Answer:

x ≈ 83.533

y = 9105.13

Step-by-step explanation:

Step 1: Substitution

109x = 79x + 2506

30x = 2506

x = 83.533

Step 2: Plug <em>x</em> in

y = 109(83.533)

y = 9105.13
