Question

What is the last step in solving 7/8 = 3x - 5/11?

A.) subtract 5/11 from both sides of the equation
B.) add 5/11 to both sides of the equation
C.) divide both sides of the equation by 3
D.) multiply both sides of the equation by 3

Answer 1

Answer:

add5/11 on both side of equations

Step-by-step explanation:

7/8=3x-5/11

7/8)+5/11)=3x

Answer 2

Answer

B.) add 5/11 to both sides of the equation

$\frac{7}{8} = 3x - \frac{5}{11}$

Adding 5/11 to both sides will give

$\frac{7}{8} + \frac{5}{11} = 3x - \frac{5}{11} + \frac{5}{11} \\ \frac{7}{8} + \frac{5}{11} = 3x$

Now, you just need to solve the fractions

$\frac{7}{8} + \frac{5}{11} = 3x \\ \frac{77 + 40}{88} = 3x \\ \frac{117}{88} = 3x \\ x = \frac{117}{88 \times 3} \\ = \frac{39}{88}$
