Answer: there are 4 solutions
x = -2
x = -1/2 = -0.500
x =(3-√5)/2= 0.382
x =(3+√5)/2= 2.618
Step-by-step explanation:
Answer:
(0,2)
Step-by-step explanation:
solve by addition/elimination
2x + 3y= 6
–3x + 5y = 10
multiply first equation by 3 and second one by 2 to eliminate x)
6x+9y=18
-6x+10y=20 (add the two equations)
6x+9y-6x+10y=38
19y=38
y=38/19=2
2x+3y=6
2x=6-6
x=0
Answer:
The answer for this is a=1,b=7,c=19.
Answer:
-2
Step-by-step explanation:
10x+30+9x+4=x-5+3
19x+34=x-2
18x=-36
x=-2
The first option :
Multiply the first equation by 8 and the second equation by 2
would not result in the elimination of the variables in this system
