Answer:
please what should we found? is it the value of ×or y
Answer:
c
Step-by-step explanation:
because the real awnser is 57/4 but simpfly
we are given

Firstly, we will simplify left side
and then we can solve for k
Left side is

we can arrange like terms



now, we can use property of exponent



now, we can equate it with right side
and we get

We can see that both sides have 30 , a and b
and they are equal
so, exponent of a must also be equal

now, we can solve for k

................Answer
1. X+2=3x-4
6=2x
x= 3
2. y= 8-x
8-x = 3x+4
4= 4x
X= 1
3. -2x +3(2x+7)=9
-2x + 6x + 21 = 9
4x = -12
x= -3
