Answer:
x=0 y=2
Step-by-step explanation:
2x+3y=6 .... 1
-5x+2y=4 .... 2
Multiply 5 with equation 1 and multiply 2 with equation 2
Then we get
10x+15y=30
-10x+4y=8
-10x and +10x get canceled so 19y=38
y=38/19=2
substitute y value in equation 1 or 2 and find the value to get x
Answer:
c =1/2
Step-by-step explanation:
2(3–5c) = 4(1–c) -1
Distribute
6 - 10c = 4 -4c -1
Combine like terms
6 - 10c =3 -4c
Add 10c to each side
6-10c+10c = 3 -4c+10c
6 = 3+6c
Subtract 3 from each side
6-3 = 3-3+6c
3 = 6c
Divide by 6
3/6 =6c/6
1/2 =c
