Question

Х+15:3×8=68. У-8×4=27

Answer 1

68:8=8,5
8,5*3=25,5
25,5-15=10,5=x

27:4=6,75
6,75+8=14,75=y

Answer 2

Х+15÷3×8=68
Х+40=68
Х=68-40
Х=28
_________
28+15÷3×8=68
68=68

У-8×4=27
У-32=27
У=27+32
У=59
__________
59-8×4=27
27=27

Answer 3

To solve the system of equations:

Х + 15 ÷ 3 × 8 = 68

У - 8 × 4 = 27

We need to simplify and isolate the variables.

Starting with the second equation:

У - 8 × 4 = 27

У - 32 = 27

У = 27 + 32

У = 59

Now we can substitute this value of У into the first equation:

Х + 15 ÷ 3 × 8 = 68

Х + 5 × 8 = 68

Х + 40 = 68

Х = 68 - 40

Х = 28

Therefore, the solution to the system of equations is Х = 28 and У = 59.
