(10x^2 - 8x - 1) + (4x^2 - 8x - 5) = 10x^2 - 8x - 1 + 4x^2 - 8x - 5 = 14x^2 - 16x - 6
1. -5x-8(-3)=9
-5x+24=9
-5x=-15
x=3
(3,-3)
2. -6x-2(-3x)=3
-6x+6x=3
0=3
No solution
3. 6x+5(-8x+2)=10
6x-40x+10=10
-34x+10=10
-34x=0
x=0
y=-8(0)+2
y=2
(0,2)
4. 6x+2(-3x-3)=-6
6x-6x-6=-6
-6=-6
Infinitely many solutions
a)
1 .we find the LCM of the denominators
2 .The answer we get we divide it with the given number denominators
4 .Again the answer we get we multiply it with the numerators .
5.And then workout
Step-by-step explanation:
a)
