Answer:
False
Step-by-step explanation:
x is 1 not zero
The value of x is 24 because 24-12=12
I worked it out by doing the opposite so by doing 12+12
Then the value of y is also 24 and I used the same method
Step-by-step explanation:
- y=3/4x+(-5)
- -4x+4(3/4x+-5)=-20
-4x+3x-20=-20
-x=-20+20
-x=0
x=0
y=3/4×{0}-5
y=-5
