Answer:
x= 1 7/12
Step-by-step explanation:
x+1/2+x+2/3-x+3/4=2
1. We know that x+x-x=x
2. 1/2+2/3-3/4=6/12+8/12-9/12=5/12
3. x+5/12=2
4. x=2-5/12
x=1 7/12
Answer:
It is a solution
Step-by-step explanation:
y = -4x - 8
Let x = -9 and y = 28
Substitute these values in
28 = -4(-9) -8
28 = 36 -8
28 =28
This is true so it is a solution
