Question

(3•a+5)•5-3=292... (c-17)•3+15=45. pls pana maine!!!!

Answer 1

(3 * a + 5) * 5 - 3 = 292
(3a + 5) * 5 = 292 + 3
3a + 5 = 295 : 5
3a = 59 - 5
a = 54 : 3
a = 18
(c - 17) * 3 + 15 = 45
(c - 17) * 3 = 45 - 15
c - 17 = 30 : 3
c = 10 + 17
c = 27

Answer 2

(3•a+5)•5-3=292
(3•a+5)•5=292+3
(3•a+5)•5=295
3•a+5=295:5
3•a+5=59
3•a=59-5
3•a=54
a=54:3
a=18

(c-17)•3+15=45
(c-17)•3=45-15
(c-17)•3=30
c-17=30:3
c-17=10
c=10+17
c=27
