7 0

Answer:

see explanation

Step-by-step explanation:

Given

10 = 7 - m ( subtract 3 from both sides )

3 = - m ( multiply both sides by - 1 )

- 3 = m , or

m = - 3

As a check

Substitute m = - 3 into the right side of the equation and if equal to the left side then it is the solution

7 - m = 7 - (- 3) = 7 + 3 = 10 = left side

Thus m = - 3 is the solution to the equation

The sum of 2 times a number and 8 is 7

My name is Ann [436]

Answer:

The number is -1/2

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2
