Answer:
x=4
Step-by-step explanation:
Four less than the product of a number and 8:
8x−4
is twice the sum of the number and 10, so
8x−4=2(x+10)
Simplify.
8x−4=2x+20
Add 4 to both sides, which is
8x=2x+24
Subtract 2x from both sides:
6x=24
Divide 6 from both sides to isolate the x
x=4
-how I got 20
8x-4=2(x+10) x=8 so 8+10=18 18+2=20
