Answer:
x = 6i, -6i
Explanation:
x² = 1 - 37 (subtract)
x² = -36 (square root both sides)
x = ±√-36 (breakdown)
x = +√-36, -√-36 (simplify)
x = 6i, -6i
Answer:
(6, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = - 3 → (1)
2x + 2y = 6 → (2)
Subtracting (1) from (2) term by term will eliminate the x- term
(2x - 2x) + (2y - 5y) = 6 - (- 3), that is
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 in either of the 2 equations and solve for x
Substituting y = - 3 in (1)
2x + 5(- 3) = - 3
2x - 15 = - 3 ( add 15 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Solution is (6, - 3 )
4/10 is equal to 2/5 because if you reduce 4/10 you get 2/5 which shows that they are equal.
