Question

13) The value of x for which 3(x-1) = 4(x-5) is
​

Answer 1

The value of x=17.

Explanation:

3(x-1) = 4(x-5)

=3x-3=4x-20

Subtract both sides by 4x.

=3x-3-4x=4x-20-4x

= −x−3=−20

Add 3 to both sides.

=−x−3+3=−20+3

−x=−17

Divide both sides by -1.

−x/-1=−17/-1

x=17

Answer 2

3x-3=4x-20
3x+17=4x
17=x
So x equals 17
