Answer 1

$s)2x + 8 = 18 \\ 2x = 18 - 8 \\ 2x = 10 \\ x = 10 \div 2 \\ x = 5 \\ t)x \div 2 - 3 = 25 \\ x \div 2 = 25 + 3 \\ x \div 2 = 28 \\ x = 28 \times 2 \\ x = 56 \\ u) {x}^{2} + 24 = 60 \\ {x}^{2} = 60 - 24 \\ {x}^{2} = 36 \\ |x| = \sqrt{36} \\ x = 6 \: \: \: \: \: o \: \: \: \: x = - 6 \\ v) \sqrt{x + 12} - 5 = 3 \\ \sqrt{x + 12} = 3 + 5 \\ \sqrt{x + 12} = 8 \\ x + 12 = {8}^{2} \\ x + 12 = 64 \\ x = 64 - 12 \\ x = 52 \\ w)x + 2x = 27 \\ 3x = 27 \\ x = 27 \div 3 \\ x = 9 \\ x)(x + 37) \div 4 = 79 \\ ( \frac{x + 37}{4} ) \times 4 = 79 \times 4 \\ x + 37 = 316 \\ x = 316 - 37 \\ x = 279$
