Answer:
13
Step-by-step explanation:
Given
x² - 14 ← substitute x = 9 into the expression
=
× 9² - 14
=
× 81 - 14
= 27 - 14
= 13
Answer:
there is no solution for these linear equations in two variables.
since a1 (y) = a2 (y)
b1 (5x) = b2 (5x)
but, c1 (12) not equal to c2 (18)
I think the answer is X=50
