Tariq's bill is 7 units
pria's bill is 5 units
the differnce is 7-5 or 2 units
the differne in their bills is $14
threfor
2unit=$14
divide by 2
1unit=$7
so tariq's bill is 7 units
1unit=$7
times 7 both sides
7units=$49
tariq's bil is $49

Answer:
When x = 0, then y = -2
When y = 0, then x = 4
Step-by-step explanation:
We are given with the following equation;
x - 2y = 4
Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.
Firstly, putting the value of x = 0;
x - 2y = 4
0 - 2y = 4
-2y = 4
y = = -2
This means that when x = 0, then y = -2.
Similarly, putting the value of y = 0;
x - 2y = 4
x - 0 = 4
x = 4
This means that when y = 0, then x = 4.
Part 1:
-3a+5(a-1)-7=
-3a+5a-5-7=
2a-11
Part 2:
a=-5
2(-5)-11=
-10-11=
-21
