What value of b will cause the system to have an infinite number of solutions? a system of equations. y equals 6 x plus b. negative 3 x plus startfraction one-half endfraction y equals negative 3.

Step-by-step explanation:

we have

----> equation A

-----> equation B

we know that

If equation A is the same of equation B, then the system of equations will have infinite solutions

Convert equation B in slope intercept form

Isolate the variable y

Multiply by 2 both sides to remove the fractions

Adds 6x both sides

 -----> equation C (slope intercept form)

Equate equation A and equation C and solve for b

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

6.5
