Answer:
Answer for the first part of question 16 is y =-24 - 8x
1st subtract 8x from both sides: 8x + y - 8x = -24 - 8x
2nd simplify: -24 - 8x
Answer for the 2nd part of Q. 16 is y = -(-4+3x)/2
1st add 3x to both sides: -3x - 2y + 3x = -4 + 3x
2nd simplify: -2y = -4 + 3x
3rd divide both sides by -2: -2y ÷ -2 = 4 ÷ -2 +3x ÷ -2
4th simplify: (-4 + 3x)/2
Answer to the 1st part of Q. 17 is y = (-1 - 2x)/3
1st subtract 2x from both sides 2x + 3y - 2x = -1 - 2x
2nd simplify: -3y= -1 - 2x
3rd divide both sides by -3: -3y ÷ -3 = 1 ÷ -3 - 2x ÷ -3
4th simplify: y = (-1 - 2x)/3
Answer to 2nd part of Q.17: y = 6 + 7x ÷ 10
1st Add 7x to both sides: -7x + 10y + 7x = 6 + 7x
2nd simplify: 10y=6+7x
3rd divide both sides by 10: 10y ÷ 10 = 6 ÷ 10 + 7x ÷ 10
4th simplify: y = 6 + 7x ÷ 10
sorry, but I don't know the answer to Q.18 but I hope I helped on questions 16 and 17 :)
