Someone help me with this please and thank you

Answer 1

(47,16)

Explanation:

System of Equations Problem.

Solve v(7)+b(6)=394;v(3)+b(12)=612

Solve 6b+7v=394 for b

Add -7v to both sides.

6b+7v+−7v=394+−7v

6b=−7v+394

Divide both sides by 6.

`b=(-7)/(6) v+(197)/(3)`

Substitute
`b=(-7)/(6) v+(197)/(3)` for b in 12b+3v=612

12b+3v=612

`12((-7)/(6) v+(197)/(3) )+3v=612`

Simplify both sides of the equation.

−11v+788=612

Add -788 to both sides.

−11v+788+−788=612+−788

−11v=−176

`(-11v)/(-11) =(-176)/(-11)`

v=16

Substitute 16 for v in
`b=(-7)/(6) v+(197)/(3)`

`b=(-7)/(6) v+(197)/(3)`

`b=(-7)/(6)(16)+(197)/(3)`

Simplify both sides of the equation.

b=47

Answer:

b=47 and v=16
