Write an value addition expression that has a value of -8

please help me with this

Step-by-step explanation:

Step 1: Subtract 2x from both sides.

7x+7−2x=2x+2−2x

5x+7=2

Step 2: Subtract 7 from both sides.

5x+7−7=2−7

5x=−5

Step 3: Divide both sides by 5.

5x

5

=

−5

5

x=−1

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
