Hi! Your answer is x = 3.

Please see an explanation for a clear and better understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Our goal is to find the value of x. That means what we have to do is to isolate x-term first.

\huge{x+10=13}

To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.

\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}

If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.

\huge{x+10=13}

Substitute x = 3 in the equation.

\huge{3+10=13}\\\huge{13=13}

The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.

Solve the equation for y.<br><br> 4.2x−1.4y=2.1
Vlada [557]

Answer:

y=3x- 3/2

Step-by-step explanation:

4.2x−1.4y=2.1

Subtract 4.2x from each side

4.2x-4.2x−1.4y=-4.2x+2.1

-1.4y = -4.2x +2.1

divide each side by -1.4

-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y

y=3x- 3/2

lesantik [10]

Answer:

t(g)= -4g + 20

Step-by-step explanation:

James is playing his favorite game at the arcade. After playing the game 3 times, he has 8 tokens remaining. He initially had 20 tokens, and the game costs the same number of tokens each time. The number tt of tokens James has is a function of gg, the number of games he plays

Solution

Let

g=No. of games James plays

t= No. of tokens James has.

Find the slope using

y=mx + b

Where,

m = Slope of line,

b = y-intercept.

Before James started playing the games, he has a total of 20 tokens.

That is, when g=0, t=20

After James played the games 3 times, he has 8 tokens left

That is, when g=3, t=8

(x,y)

(0,20) (3,8)

m=y2-y1 / x2-x1

=(8-20) / (3-0)

= -12 / 3

m= -4

Slope of the line, m= -4

y=mx + b

No. of tokens left depend on No. of games James plays

t is a function of g.

t(g)

t(g)= -4g + 20
