1
Add 2 to both sides:
Divide both sides by -4 (this is negative, so we have to swap the inequality sign):
2
Expand the left hand side:
Add 8 and y to both sides:
Divide both sides by 3
3-4
Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them

Answer:
14
Step-by-step explanation:
7/8 ÷ 1/16 = 7/8 × 16/1
7/8 × 16/1 = 14
Answer:
12
Step-by-step explanation:
If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;

sub 9 forx
f(9)=5(9)-16
f(9)=45-16
f(9)=29
f(9)=29
