Answer: x = 9
Step-by-step explanation:
2x^2 • x^2 = 2x^4
First, multiply the terms with the same base by adding their exponents
2x^2+2
Then, add the numbers
2x^4
Answer:
1.6666666667
Step-by-step explanation: remove the decimal points.
This is an odd question because it's a little subjective, but, for me, I would choose x from the second equation because you could simply add 12y to both sides, then divide by 3. It has the added benefit of not having any decimals/fractions, or negative values, which would be nice for substitution.
Plug x=3 in the first equation to find y:
4(3)+5y=2
y=-2
so a=-2
Next, plug x=3, y=-2 in the second equation to find b:
6(3)-2(-2)=22
b=22
