Step-by-step explanation:
1. 9x^5
2. 9x^6
3. 27x^5
4. 27x^6
3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
Answer:
25x + 10y
Step-by-step explanation:
if you replace x with 4 and y with 6, you will find out that it is equal to 160
