Solve for m. −7m=42 (1 point) Responses

Answer 1

To solve for m in the equation −7m = 42, we need to isolate m.

First, we can divide both sides of the equation by -7:

-7m/-7 = 42/-7

This simplifies to:

m = -6

Therefore, the value of m is -6.

Answer 2

k/-2=-10

Answer 3

To solve for k in the equation k/-2 = -10, we need to isolate the variable k.

Step 1: Multiply both sides of the equation by -2, which is the reciprocal of -1/2:

(k/-2) * -2 = -10 * -2

Simplifying this will give us:

k = 20

Therefore, the value of k that solves the equation k/-2 = -10 is k = 20.

Answer 4

5y-10=-25

Answer 5

To solve for y in the equation 5y - 10 = -25, we need to isolate the variable y.

Step 1: Add 10 to both sides of the equation:

5y - 10 + 10 = -25 + 10

Simplifying this will give us:

5y = -15

Step 2: Divide both sides of the equation by 5:

(5y)/5 = (-15)/5

Simplifying this will give us:

y = -3

Therefore, the value of y that solves the equation 5y - 10 = -25 is y = -3.

Answer 6

Solve for x. −3x + 4 = −8

Answer 7

To solve for x in the equation −3x + 4 = −8, we need to isolate the variable x.

Step 1: Subtract 4 from both sides of the equation:

−3x + 4 - 4 = −8 - 4

Simplifying this will give us:

−3x = -12

Step 2: Divide both sides of the equation by -3:

(−3x)/-3 = (-12)/-3

Simplifying this will give us:

x = 4

Therefore, the value of x that solves the equation −3x + 4 = −8 is x = 4.
