Answer:
The answer to your question is: x = 3.7
Step-by-step explanation:
5x+2y=22 (1)
- 2x+6y=3 (2)
Multiply (1) by -3
-3 ( 5x+2y=22 ) = -15x -6y = -66
Solve by elimination
-15x -6y = -66
- 2x+6y=3
- 17 x = -63
x = -63 / -17
x = 3.7
-2(3.7) + 6y = 3
-7.4 + 6y = 3
6y = 3 + 7.4
6y = 10.4
y = 1.7
Answer:
x = 63/17 ≅ 3.7
y = 59/34 ≅ 1.7
Step-by-step explanation:
5*x+2*y=22 (1)
-2*x+6*y=3 (2)
First, isolate x in the first equation, to get
5*x=22 - 2*y
x = 22/5 - (2/5)*y (3)
Then, replace eq. 3 into eq. 2, as follows
-2*[22/5 - (2/5)*y] + 6*y = 3
-44/5 + (4/5)*y + 6*y = 3
(34/5)*y = 3 + 44/5
y = (59/5)*(5/34)
y = 59/34 ≅ 1.7
Replacing this value in eq.1, we get
5*x+2*(59/34) = 22
5*x = 22 - 59/17
x = (315/17)*(1/5)
x = 63/17 ≅ 3.7
