Question

Solve the following equation.
8x + 4 = 3(x-1) + 10​

Answer 1

Answer:

8x + 4 = 3 (x - 1) + 7

or 8x + 4 = 3x - 3 + 7 = 3x + 4

Transposing 3x to the LHS and 4 to the RHS, we get

8x - 3x = 4 - 4 = 0

5x = 0

Dividing both sides by 5:

x = 0

Check :- Putting x = 0 in both LHS and RHS:

LHS :- 8x + 4 = 8(0) + 4 = 4

RHS :- 3(x-1) + 7 = 3(-1) + 7 = -3 + 7 = 4

Hence, LHS = RHS

Answer 2

Answer:

5/3 OR 1.666

Step-by-step explanation:

8x + 4 = 3x - 3 + 10

=> 8x - 3x = 10 - 3 - 4

=> 5x = 3

=> x = 5/3

=> x = 1.666
