Question

(4.x)÷5-2=18como faço está conta​

Answer 1

$\frac{\left(4\cdot \:5\right)}{5}-2=18\\\\\frac{4\cdot \:5}{5}-2\\\\\frac{4\cdot \:5}{5}\\\\=\frac{20}{5}\\\\\frac{20}{5}=4\\=4\\\\=4-2\\\\=2\\\\2=18$

Answer 2

(4 · x) ÷ 5 - 2 = 18

4x ÷ 5 = 18 + 2

4x ÷ 5 = 20

4x = 20 · 5

4x = 100

x =  $\frac{100}{4}$

x = 25
