Answer:
the first number equals 6
the second number equals 10
Step-by-step explanation:
3×n1 + 5×n2 = 68
3×n2 - 4×n1 = 6
3×6 + 5×10= 68
\/ \/
18 + 50= 68
3×10 - 4×6 = 6
30 - 24 = 6
hope this helped :)
It would be at a depth of 42 meters below the surface
13(6)=78 -120+78=-42
4x + 6 = 18
-6 is solution ?
4 * (-6) + 6 = 18 ?
-24 + 6 = - 18
so not the solution
3 is solution ?
4 * 3 + 6 = 18 ?
4 * 3 + 6 = 12 + 6 = 18
YES
