Hey there!


3x - 7 = 20°


ADD 7 to BOTH SIDES

3x - 7 + 7 = 20 + 7

CANCEL out: -7 + 7 because it give you 0

KEEP: 20 + 7 because it help solve for the x-value


NEW EQUATION: 3x = 20 + 7


SIMPLIFY IT!


3x = 27


DIVIDE 3 to BOTH SIDES

3x/3 = 27/3

CANCEL out: 3/3 because it give you 1

KEEP: 27/3 because it help solve for the x-value


NEW EQUATION: x = 27/3


SIMPLIFY IT!

x = 9



Therefore, your answer is: x = 9



Good luck on your assignment & enjoy your day!

Answer:x=9

Step-by-step explanation:so this is a isosceles triangle so that means the two sides are equal so set up the equation as 3x-7=20. And by moving the 7 over it will be 3x=27 and then you want you separate the x and to do that you have to divide x and 27 by 3 and you answer is x = 9

Answer:

Step-by-step explanation:

100   25

4 is the hundredths place, not hundreds because hundredths is a fraction of a whole. So its 4 over the value of its place which is 1 hundredths and 4 goes into itself 1 and 4 goes into 100,  25 times.

9(n+3)=7n-3 Help Me Find "X"
Y_Kistochka [10]
9(n+3)=7n-3

1) distribute 9 into (n+3)

9n+27=7n-3

2) subtract 7n on both sides

2n+27=-3

3) subtract 27 on both sides

2n=-30

4) divide by 2

n=-15
