\huge \bf༆ Answer ༄

Let's solve ~

A. 5(x - 4) = 10


  • \sf5(x - 4) = 10


  • \sf(x - 4) = 10 / 5


  • \sf \: x - 4 = 2


  • \sf x = 2 + 4


  • \sf x = 6

B. 2x(4x + 3x) = 21


  • \sf2x(4x + 3x) = 21


  • \sf2x(7x) = 21


  • \sf14 {x}^(2) = 21


  • \sf {x}^(2) = 21 / 14


  • \sf x {}^(2) = (3)/(2)


  • \sf x = \sqrt{ (3)/(2) }

C. 3(4 - 2x) = 28


  • \sf3(4 - 2x) = 28


  • \sf12 - 6x = 28


  • \sf - 6x = 28 - 12


  • \sf x = 16 / - 6


  • \sf x = - (8)/(3)

D. 10x(2 + 13) = 300


  • \sf 10x(2 + 13) = 300


  • \sf10x(15) = 300


  • \sf10x = 300 / 15


  • \sf x = 20 / 10


  • \sf x = 2

I hope it helps ~
