Answer:
Step-by-step explanation:
2x + 3y = 2
x = 2 - 3y /2
x + y = 0
substitute the value of x
+ y = 0
2 - 3y + 2y = 0
2 = y
again,substitute the value of y
x = 2 - 3y / 2
=2 - 3*2 / 2
=2 - 6 / 2
=-2

Answer:
x = -13 or 2
Step-by-step explanation:
x² + 11x + ¹²¹/₄ = ¹²⁵/₄
(x + ¹¹/₂)² = ¹²⁵/₄
x + ¹¹/₂ = ±¹⁵/₂
x = -¹¹/₂ ± ¹⁵/₂
x = -13 or 2
