Answer:
since equation 1 says that X= 1
any other equation saying x=1 will be valid!
Equation A
Equation B
Equation C
Equation D
all correct
If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.
the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130
Hope this helps!

Answer: x = 1/2, y = 4
Step-by-Step Explanation:
Lets solve it using Substitution Method :-
=> 2x + 3y = 13 (Eq. 1)
=> 4x - y = - 2 (Eq. 2)
From Eq. 2 :-
=> 4x - y = - 2
= - y = - 2 - 4x
=> y = 4x + 2 (Eq. 3)
Substitute value of ‘y’ in Eq. 1 :-
=> 2x + 3y = 13
= 2x + 3(4x + 2) = 13
= 2x + 12x + 6 = 13
= 14x = 13 - 6 = 7
=> x = 7/14 = 1/2
Substitute value of ‘x’ in Eq. 3 :-
=> y = 4x + 2
= y = 4(1/2) + 2
= y = 4/2 + 2
=> y = 2 + 2 = 4
Therefore; x = 1/2, y = 4
