Find the solution to the systems of equations using the elimination method.
2 answers:
X=-2/3y+11/3
x=-3/5y+14/5
Answer:
x = 1 ; y = 3
Step-by-step explanation:
5(2x + 3y = 11)
2(5x + 3y + 14)
(distribute)
10x + 15y = 55
10x + 6y = 28
(subtract)
9y = 27
(divided 9 to both sides)
9 divided by 9 cancels out and 27 divided by 9 = 3
so..
y = 3
now, using any equation, (i’ll be using 2x + 3y =11) plug in the y value to find the x value
2x + 3y = 11
2x + 3(3) = 11
(multiply 3 x 3)
2x + 9 = 11
(subtract 9 from 9 and 11)
2x = 2
(divide 2 from both sides)
2 divided by 2 = 1
therefore...
x = 1
