6(a+3)=2a+30 what is the answer

a = 3

Step-by-step explanation:

6(a+3)=2a+30

Distribute

6a + 18 = 2a+30

Subtract 2a from each side

6a + 18 -2a= 2a+30-2a

4a  +18 =30

Subtract 18 from each side

4a+18-18 = 30-18

4a = 12

Divide each side by 4

4a/4 = 12/4

a = 3

the answer is 31.27mph

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
