Solve for the equation

13/2 -1/2x= -x +7/3

0.1167 or -4.2833

Step-by-step explanation:

13/2 -1/2x= -x +7/3

Collect like terms

-1/2x+x=7/3-13/2

Using LCM

(-1+2x²)/2x=(14-39)/6

(-1+2x²)/2x=-25/6

Cross multiply

6(-1+2x²)=-25(2x)

-6+12x²=-50x

12x²+50x-6

Solve using formulae method

-b±(√b²-4ac)/2a

Where a=12, b=50 and C=-6

(-50±(√50²-4(12)(-6)))/2(12)

(-50±(√2500+288))/24

(-50±√2788)/24

(-50±52.8)/24

(-50+52.8)/24 or (-50-52.8)/24

2.8/24 or -102.8/24

0.1167 or -4.2833

x = -25/3

Step-by-step explanation:

13/2 -1/2x= -x +7/3

Multiply each side by 6 to get rid of the fractions

6(13/2 -1/2x)= 6*(-x +7/3)

39 -3x = -6x +14

Add 6 to each side

39 -3x+6x = -6x+6x +14

39 +3x = 14

Subtract 39 from each side

39-39 +3x = 14-39

3x = -25

Divide each side by 3

3x/3 = -25/3

x = -25/3

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 : )
