Answer:

16 = a

Step-by-step explanation:

6 = a/4 +2

Subtract 2 from each side

6-2 = a/4 +2-2

4 = a/4

Multiply each side by 4

4*4 = a/4*4

16 = a

Answer:

D.) 16

Step-by-step explanation:

6=\frac{a}{4}+2

Use inverse operations to isolate a.

Subtract 2 from both sides:

6-2=\frac{a}{4}+2-2\\\\4=\frac{a}{4}

Multiply 4 to both sides:

4*(4)=4*(\frac{a}{4} )\\\\16=a\\\\a=16

Finito.

Solve the system by substitution. Check your solution.
postnew [5]

Answer:

(9,126)

Step-by-step explanation:

Make sure x and y are on the same side

0.5x+0.25y=36\\16x-1y=18

Eliminate y by multiplying the first equation by 4 then adding both equations together

2x+1y=144\\16x-1y=18\\18x=162\\x=9

Plug the x value (9) into one of the equations

16(9)-1y=18

Solve

16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y

x=9, y=126
