Answer:
x = 4
y = -3
Step-by-step explanation:
2x + 4y = -4
x + 2y = -2 ---------(1)
3x + 5y = -3 ----------(2)
Equation (1) multiplied by 3 then subtracted from equation (2),
(3x + 5y) - 3(x + 2y) = -3 + 6
-y = 3
y = -3
From equation (1)
x + 2(-3) = -2
x - 6 = -2
x = 6 - 2
x = 4

Simplify the expression:
2x^4 - 10x^3 / 6x
Answers
Answer:
(x^2(6x^2)-5)/3
Step-by-step explanation:
Given the expression
2x^4 - 10x^3 / 6x
On simplifying
2x^4 - 10x^3 / 6x
= 2x^4 - 10x^2/6
= [6(2x^4)- 10x^2]/6
= 12x^4 - 10x^2/6
= 2x^2(6x^2)-5/6
= (x^2(6x^2)-5)/3
hence the simplified form of the expression is (x^2(6x^2)-5)/3
