Answer:
15
Step-by-step explanation:
4x+y=8 so the answer is 15?
I rather not..............
in step 2 he made his first mistake
1/2(n-4)-3=3-(2n+3)
1/2n-4/2-3=3-(2n+3)
1/2n-2-3=3-(2n+3)
in the second step he put 5 instead of 2.
First work out the parenthesis. Division goes first so 0.12/0.3 = 0.4. 0.8-0.4-0.4. (Sorry for so many dots o_o) 4.92 divided by 0.4 equals 12.3
