Question

A) (x*3+47)-315=146
B) (x:6-528)+307=517

Answer 1

a)

(3x+47)-315=146

3x+47=146+315

3x+47=461

3x=461-47

3x=414

x=414:3

x=138

b)

(x:6-528)+307=517

x:6-528=517-307

x:6-528=210

x:6=210+528

x:6=738

x=738×6

x=4428

Answer 2

A) ( x × 3 + 47 ) - 315 = 146
x × 3 + 47 = 146 + 315
x × 3 + 47 = 461
x × 3 = 461 - 47
x × 3 = 414
x = 414 : 3
x = 138

B) ( x : 6 - 528 ) + 307 = 517
x : 6 - 528 = 517 - 307
x : 6 - 528 = 210
x : 6 = 210 + 528
x : 6 = 738
x = 738 × 6
x = 4 428
