Answer:
-18 + x = 11
x = 29
Step-by-step explanation:
To solve this, you can use the formula of a + b = c
Answer:
3 (5x+2y = 0)
2 (2x – 3y = -19)
Step-by-step explanation:
5x+2y=0 (1)
2x-3y=-19 (2)
To eliminate y from the first two equation when applying the linear combination method
We will multiply y Equation (1) and (2) with 3 and 2 respectively so that the coefficients of y in the two equations +6 and -6 respectively
3(5x+2y=0)
2(2x-3y=-19)
We have,
15x+6y=0 (3)
4x-6y= -38 (4)
Add Equation (3) and (4)
19x=-38
x= -2
Substitute x= -2 into (1)
5x+2y=0
5(-2)+2y=0
-10+2y=0
-10= -2y
y=-10/-2
=5
y=5, x=-2
Since you have exponents this is what you end up getting.
I only used the calculator for the multiplying. (Also I used * for multiplying)
(12x^4+5x^3+3x^2-5)/(x+1)
(12x*x*x*x+5x*x*x+3x*x-5)/(x+1)
(12+5+3-5)/(x+1)
(15)/(x+1)
You divide.
You get 15.
Now you add up the x's.
15x^9 plus another x because of the one in the other parentheses.
