Answer 1

Solve for x
.
−7x=−84
(1 point)

Answer 2

Solve for x
.
x5=20
(1 point)

Answer 3

x/5=20

Answer 4

To solve the equation \( x - 12 = -13 \), follow these steps:

1. Add 12 to both sides of the equation to isolate \( x \):
\[
x - 12 + 12 = -13 + 12
\]

2. This simplifies to:
\[
x = -1
\]

Thus, the solution is:
\[
\boxed{-1}
\]

Answer 5

To solve the equation \(-7x = -84\), follow these steps:

1. Divide both sides by \(-7\) to isolate \(x\):
\[
x = \frac{-84}{-7}
\]

2. This simplifies to:
\[
x = 12
\]

Thus, the solution is:
\[
\boxed{12}
\]

Answer 6

To solve the equation \( x^5 = 20 \), follow these steps:

1. Take the fifth root of both sides of the equation:
\[
x = \sqrt[5]{20}
\]

2. This can also be expressed using exponent notation:
\[
x = 20^{1/5}
\]

Therefore, the solution is:
\[
\boxed{20^{1/5}}
\]

If you need a numerical approximation, \( 20^{1/5} \approx 2.58 \).

Answer 7

To solve the equation \( \frac{x}{5} = 20 \), follow these steps:

1. Multiply both sides by 5 to isolate \( x \):
\[
x = 20 \times 5
\]

2. This simplifies to:
\[
x = 100
\]

Thus, the solution is:
\[
\boxed{100}
\]
