Answer:
Step-by-step explanation:
We have been two algebraic expressions which is given below:
We have to find the value of x - y. so we need to find the value of x and y.
4x - y = 1 * 3
3x + 2y = 20 * 4
- 12x - 3y = 3
- 12x + 8y = 80
--------------------
-11y = - 77
y = 77/11
y = 7
- <u>Substitute the value of y in equation 1.</u>
4x - y = 1
4x - 7 = 1
4x = 1 + 7
4x = 8
x = 8/4
x = 2
- x - y
- 2 - 7 = -5
- Therefore, the required value of x, y , and x - y are 2,7 and -5 respectively.
Is think your answer is x=y+5

Answer:
Monkey: -5/2
Step-by-step explanation:
monkey = x
3x + 4 = -x - 6
3x + x = -6 - 4
4x = -10
4x/4 = -10/4
x = -5/2
Check:
3x + 4 = -x - 6
3(-5/2) + 4 = -(-5/2) - 6
-15/2 + 4 = 5/2 - 6
-15/2 + 8/2 = -3.5
-7/2 = -3.5
-3.5 = -3.5
