Hey guys

I need help my brain isn’t working today

It's okay my brain doesn't work some days, too.

1. x = -7

2. x = -6

3. x = -1

4. y = 4

Step-by-step explanation:

1. Simply subtract equal and opposite values from positive values and do the same on both sides. Divide the final x value by its coefficient to get 1x = -7

2. Do the same as above AFTER distributing the 4(5 - x)

3. Once again, distribute all values then combine like terms like #1

4. This one uses a fraction to distribute, but it is just like dividing the number by 3 instead of multiplying (6/3 instead of 6 * 3)

Hope I helped!

i dont know sorry

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
