Ciara solved the exponential equation 3x+1 = 15 and her work is shown below. What is the first step she did incorrectly?

The step that she did incorrectly would be step 3. For this we need to isolate the variable x. So, dividing x+1 should not be done because you are limiting the domain which is not main goal here. I hope this answers the question. Have a nice day.

5g + 4(-5+3g) = 1 - g

Korvikt [17]

5g + 4(-5 + 3g) = 1 - g
5g - 20 + 12g = 1 - g
17g - 20 = 1 - g
$\frac{18g}{18} = \frac{21}{18}$
there can be to answer
g = $\frac{21}{18}$ or
you can simplify $\frac{21/3}{18/3} = \frac{7}{6}$ or $1 \frac{1}{6}$

Kimiya has four times as many marbles as Ramneet. If kimiya gave 18 to Ramneet they would have the same number. How many marbles

RSB [31]

Answer:

Kimiya has 48 marbles, Ramneet has 12 marbles

Step-by-step explanation:

kimiya has 4x marbles ramneet has x marbles then 4x - 18 = x + 18 because if you give 18 marbles from kimiya to ramneet then you subtract 18 from kimiya and add 18 to ramneet by solving the equation you will get x as 12.So kimiya has 48 marbles, ramneet has 12 marbles.
