Solve the equation 43x 5 256SolutionIf the problem is 43x

Solve the equation. 4(3x - 5 ) = 256

If the problem is 4(3x-5) = 256

Divide both sides by 4: 3x-5 = 64

Add 5 on both sides: 3x = 69

Divide by 3 on both sides: x = 69/3 = 23

Solution : x= 23

If the problem is : 4^(3x - 5 ) = 256

writing 256 = 16*16 = 4^4

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

equate the exponents on both sides:

3x-5 = 4 ----> 3x =9

x =3
