Y=x-2
X=
Y=
Answer:
Step-by-step explanation:
10x-9y=24....(1)
y=x-2...(2)
Substitute (2) into (1)
10x-9(x-2)=24
10x-9x+18=24
x+18=24
Substrate 18 from both sides
x=6
Substitute the value of x in (2)
y=6-2
y=4
When x=6,y=4
Answer:
a = p/10 - (3 b)/10
Step-by-step explanation:
Solve for a:
p = 10 a + 3 b
p = 10 a + 3 b is equivalent to 10 a + 3 b = p:
10 a + 3 b = p
Subtract 3 b from both sides:
10 a = p - 3 b
Divide both sides by 10:
Answer: a = p/10 - (3 b)/10
