Question

a) x/2 + 4 = 2× b) x/2 +x/3 = 1​

Answer 1

a)

$\frac{x}{2}+4=2x\\\frac{x}{2}+4-4=2x-4\\\frac{x}{2}=2x-4\\\frac{x}{2}\cdot \:2=2x\cdot \:2-4\cdot \:2\\x=4x-8\\x-4x=4x-8-4x\\-3x=-8\\\frac{-3x}{-3}=\frac{-8}{-3}\\x=\frac{8}{3}$

✅ x = 8/3

b)

$\frac{x}{2}+\frac{x}{3}=1\\\frac{x}{2}\cdot \:6+\frac{x}{3}\cdot \:6=1\cdot \:6\\3x+2x=6\\5x=6\\\frac{5x}{5}=\frac{6}{5}\\x=\frac{6}{5}$

✅ x = 6/5
