Answer: True
Step-by-Step Explanation:
=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3
Substitute values of ‘x’ and ‘y’ in Eq. 1 :-
=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS
Therefore, it is a Solution.
Answer:
.
Step-by-step explanation:
(x+2)(x+4)
=x(x+4)+2(x+4)
=x²+4x+2x+8
=x²+6x+8
These two parallel lines are cut by a transversal, through the properties of a transversal, we know tht opposite exterior angles are congruent.
therefore, set the two angles equal to each other.
-1+14x=12x-17
add 1 to both sides
14x=12x-16
subtract 12x from both sides
2x=-16
divide both sides by 2
x=-8
