4x-24=1000

=> 4x = 1000+24

=> 4x = 1024

=> x = 256

2)Given , 7x= 343

=> x = 343/7

=> x = 49

3) given , x^4 = 4096

=> x = fourth root of 4096

Answer with step-by-step explanation:

1) 4x - 24 = 1000

Add 24 to both sides.

4x = 1024

Divide both sides by 4.

x = 256

2) 7x = 343

Divide both sides by 7.

x = 49

3) x⁴ = 4096

Find 4th root of both sides.

x = 8
