Because they do not have like bases.
Answer:
The answer is 4
Step-by-step explanation:
2(2/3)2(1/2)3
Step-by-step explanation:
5x-6+7x+18=180
12x=180+6-18
12x=168
168÷12=14
X=14
for y
3y+11=7x+18(7×14+18)
3y+11=116
3y=116-11
3y=105
y= 35
Answer:

Step-by-step explanation:
put them both in exponential form and then since they are both base 6, you can add the exponents.

(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
