Hey there!
4x - 9 = 15
ADD 9 to BOTH SIDES
4x - 9 + 9 = 15 + 9
CANCEL out: -9 + 9 because it gives you 0
KEEP: 15 + 9 because it help solve for the x-value.
NEW EQUATION: 4x = 15 + 9
SIMPLIFY IT!
4x = 24
DIVIDE 4 to BOTH SIDES
4x/4 = 24/4
CANCEL out: 4/4 because it gives you 1
KEEP: 24/4 because it gives you the answer of the x-value
NEW EQUATION: x = 24/4
SIMPLIFY IT!
x = 6
Therefore, your answer is: x = 6 (Option D.)
Good luck on your assignment and enjoy your day!

Here,
= 12 + 4 - 4X + 3 + 21 - 8 + 7X + 8
= 40 + 3X

thank you
So what we know is that there is a number 1?2 that is divisible by 11.
what was 11 multiplied by to get this number? it must start with "1" since 1*1=1 and end with "2" since 1*2=2 and there is 2 at the end of the product .
so let's try: what is 11*12? 132? yes, that sounds good!
so the missing number is 3 and they each paid 12 dollars.
<u>Given</u>:
The given figure shows the intersection of the two lines.
The angles formed by the intersection of the two lines are (3x - 8)° and (2x + 12)°
We need to determine the equation to solve for x and to find the value of x.
<u>Equation to solve for x:</u>
Since, the two angles (3x - 8)° and (2x + 12)° are vertically opposite angles and the vertical angles are always equal.
Hence, we have;
Thus, the equation to solve for x is
<u>Value of x:</u>
The value of x can be determined by solving the equation
Thus, we have;
Thus, the value of x is 20.
