Answer:
a. 2.5
b. 2.333
c. 2.85
Step-by-step explanation:
A) 1. subtract -x on both sides 2. to get 3x-1/2=7
3. Add 1/2 on both sides 4. to get 3x=7.5
5. divide 3 on both sides 6. To get... x=2.5
B)1. Same process. 2. x+2=13/3
3. x=13/3-2 4. x= 2.33(repeating)
C) 1. same process. 2. 2x-x/3=3+7/4
3. 2x-x/3=4.75 4. Isolate -x/3
5.-x/3=4.75-2x 6. multiply both sides by 3
7. -x=14.25-6x 8. 5x=14.25
9. x= 2.85
* remember to distribute the 3 to each variable.
Answer:
1) 4x-1/2 = x + 7
Answer : x=5/2
2) 3x + 2 = 2x+13/3
Answer: x=7/3
Step-by-step explanation:
1) 4x-1/2 = x + 7
Solution
Let's solve your equation step-by-step.
4x−1/2=x+7
Step 1: Simplify both sides of the equation.
4x+−1/2=x+7
Step 2: Subtract x from both sides.
4x+−1/2−x=x+7−x
3x+−1/2=7
Step 3: Add 1/2 to both sides.
3x+−1/2+1/2=7+1/2
3x=15/2
Step 4: Divide both sides by 3.
3x/3=15/2/3
x=5/2
2) 3x + 2 = 2x+13/3
Solution
Let's solve your equation step-by-step.
3x+2=2x+13/3
Step 1: Subtract 2x from both sides.
3x+2−2x=2x+13/3−2x
x+2=13/3
Step 2: Subtract 2 from both sides.
x+2−2=13/3−2
x=7/3
