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!

50 & 52 make the statement true
Answer:
B = 49/5 - 7a/5
A = = -5b/7 + 7
Step-by-step explanation:
Given that,
7a+ 5b= 49
Solution:
<em>Solving for a:</em>
Add -5b to both sides:
Divide both sides by 7:
Hence,a = -5b/7 + 7.
<em>Solving for b:</em>
Add -7a to both sides:
Divide both sides by 5:
Hence,b = 49/5 - 7a/5.
To solve the equation 54m = 51^2 we first calculate the square of 51. We can rewrite our equation as 54m = 2601. Now we divide by 54 on both sides to get m = 2601/54. 2601 is not divisible by 54, but we can simplify 2601/54 to 289/6 by dividing by 9 on both sides.
