Answer:
8
Explanation:
first we will just solve the expression 2(4x +6)=78
1. use destributive property with 2(4x + 6)
2*4x=8x
2*6=12
(8x+12)=78
2. now that the expression is simplified down we will subtract 6 by 6 to isolate it
6-6+=0
78-6=72
3. now we can divide 8x by 8 also divide 78 by 8
8x/8=0
78/8= 9.75
