Answer:
x = 0
y = 1
Step-by-step explanation:
y = 4x + 1 -------eqn 1
y = x + 1 -------eqn 2
Looking for x, let's use eqn 1
y = 4x + 1
4x = y - 1
Divide both sides by 4, to get x
4x/4 = (y - 1) / 4
x = (y - 1) / 4
Substitute the value of x into eqn 2
y = x + 1
y = (y - 1) / 4 + 1
LCM = 4
y =( y - 1 + 4)/4
y =( y + 3) / 4
Cross multiply
y * 4 = y + 3
4y = y + 3
4y - y = 3
3y = 3
Divide both sides by 3, to get y
3y / 3 = 3/3
y = 1
Substitute y = 1 , into eqn 1
y = 4x + 1
1 = 4x + 1
1 -1 = 4x
0 = 4x
Divide both sides by 4, to get x
0/4 = 4x/4
0 = x
x = 0
Hint, let's check if the values are correct
Let's pick eqn 2
y = x + 1
y = 1
x = 0
1 = 0 + 1
1 = 1
Correct
Let's try the eqn 1
y = 4x + 1
1 = 4(0) + 1
1 = 0 + 1
1 = 1
Correct too
Answer:
30% members have voted.
Step-by-step explanation:
Given:
Number of members voted = 3
Number of members didn't vote = 7
We need to find what percentage of people voted.
Solution:
First we will find the total number of members in the election.
Now we can say that;
The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.
framing in equation form we get;
The total number of members in the election = 
Now we will find the percentage of people voted.
So we can say that;
Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;
Percentage of members voted = 
Hence 30% members have voted.

Answer:
24
Step-by-step explanation:
First do parenthesis:
3*(9+1)-6 -> 3*(10)-6
Then do multiplication:
3*(10)-6 -> (30)-6
Then complete it with subtraction:
(30)-6 -> (24)
So your answer would be 24!
