Question

C) 3x - 1÷2=4 solve for x​

Answer 1

Answer: x = 1.5 :)

Explanation:

first move the -1/2 to the other side of the equation (the side with the 4) and flip the sign (turn the - to a +).

4 + 1/2 = 4.5

Next divide the 4.5 by the coefficient (3) on the other side of the equation.

4.5/3 = 1.5

Answer 2

`\tt x = 3/ 2` or 1.5

Explanation:

3x - 1÷2=4

Solving for x in the equation:

`\sf 3x - (1)/(2)=4`

`\sf \textsf{Adding both side by } (1)/(2)`

`\sf 3x = 4 + (1)/(2)`

`\sf 3x = (4*2+1)/(2)`

Dividing both sides of the equation by 3:

`\sf x = (9)/(2) / 3`

Simplify the right side of the equation:

`\sf x = (9)/(2)*(1)/(3)`

`\tt x = (9)/(2*3)`

`\sf x = (3)/(2)`

Therefore, the value of x is
`\tt x = 3/ 2`
