5 x-2 =8
Adding 2 on both sides
→5 x-2+2=8+2
→5 x=10
Dividing both sides by,5, we get
→x=2
Using the concept of Logarithms
Gives, x=2.005 (Approx)
Answer:12,24,32 44,56
Step-by-step explanation:
1. Line 3 is the first error. In order to get rid of the 25, you add it to both sides, not subtract. So, your answer is B.
2. Line 1 because it says in the question "4
less than a number" and the equation adds 4, instead of subtracting. Your answer is A.
3. Line 4. To get rid of the 6 in front of 6x, you have to divide by it, but instead they multiply. So, your answer is C.
4. To solve this, you will use the distributive property first:
Turns into:
Get rid of the 12:
Divide by 4:
Your answer is B.
5. You have to set it up:
Just solve for x:
Multiply both sides by 3 to isolate x:
Your answer is B.
