Answer 1

• $2x - 3 = 5 \\ x = 5 + 3 \div 2 \\ x = 8 \div 2 \\ x = 4 \\ \\ 2(4) - 3 = 5$
• $3y + 2 = 1 \\ y = 1 - 2 \div 3 \\ y = - 1 \div 3 \\ y = - 0.333 \\ \\ 3( - 0.333) + 2 = 1$
• $9x - 6 = 18 \\ x = 18 + 6 \div 9 \\ x = 24 \div 9 \\ x = 2.666 \\ 9(2.666) - 6 = 18$
• $5x + 7 = 3 \\ x = 3 - 7 \div 5 \\ x = - 4 + \div 5 \\ x = - 0.8 \\ 5( - 0.8) + 7 = 3$
