Answer:
Part A) x co-ordinate is -4
Part B) x =1 and y = 2
Step-by-step explanation:
Part A
Given:
Two equations are given.
-----------(1)
Substitute -in equation 1
Apply rule
x=-4
Therefore, the coordinate of x is -4
Part B
Given:
Two equations are given:
-------(1)
---------(2)
solve equation 1
----------(3)
substitute in equation 2.
y = 2
Now, we substitute y = 2 in equation 3.
x = 1
Therefore, The value of y =2 and x = 1
