Answer:
y = 21
x = 74
Step-by-step explanation:
-x + 4y = 10
x - 3y = 11
Let the first eqn be eqn 1 and the second be eqn 2
ie
- x + 4y = 10 --------eqn 1
x - 3y = 11 ----------eqn 2
From eqn 1, make x the subject of the formula
Carrying x over the equal to in order to change the sign from - to +
4y - 10 = x
Substitute the value of x in eqn 2
4y - 10 - 3y = 11
Collecting like terms
4y - 3y = 11 + 10
y = 21
The value of y is 21
Then, substitute the value of y into eqn 1
-x + 4y = 10
-x + 4(21) = 10
-x + 84 = 10
84 -10 = x
In order to get rid of the - sign
x = 74
Therefore,
x = 74
y = 21
Y=-2/19x-13/19 is the answer

2(9)-3(3)=9
Answer:
-1
Step-by-step explanation:
k + (2k - 10) =
= 3 + (2 * 3 - 10)
= 3 + (6 - 10)
= 3 + (-4)
= -1
