1st equation—x, substitute y:
<span>3x + 2(x + 3) = 16 </span>
<span>3x + 2x + 6 = 16 </span>
<span>5x = 10 </span>
<span>x = 2 </span>
<span>y in the above equation: </span>
<span>= 2 + 3 </span>
<span>= 5 </span>
<span>Answer: x = 2, y = 5</span>
This is experimental. Saul has conducted an experiment to come to this solution
no it is not equal. its because you are multiplying one by 3 and the other by 2. you have to multiply them by the same number for them to be equal
To solve for scientific notation you move the decimal to the left until you hit a whole number. In your case it’s 5. So when you write it it’s 8.55*10^-5. It’s -5 because you’re having to move the decimal to the left. (Left is negative and right is positive). Hope this helps!
