Help me plz:

Answer 1

$\huge \bf༆ Answer ༄$

Let's solve ~

A. 5(x - 4) = 10

• $\sf5(x - 4) = 10$

• $\sf(x - 4) = 10 \div 5$

• $\sf \: x - 4 = 2$

• $\sf x = 2 + 4$

• $\sf x = 6$

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

• $\sf2x(4x + 3x) = 21$

• $\sf2x(7x) = 21$

• $\sf14 {x}^{2} = 21$

• $\sf {x}^{2} = 21 \div 14$

• $\sf x {}^{2} = \dfrac{3}{2}$

• $\sf x = \sqrt{ \dfrac{3}{2} }$

C. 3(4 - 2x) = 28

• $\sf3(4 - 2x) = 28$

• $\sf12 - 6x = 28$

• $\sf - 6x = 28 - 12$

• $\sf x = 16 \div - 6$

• $\sf x = - \dfrac{8}{3}$

D. 10x(2 + 13) = 300

• $\sf 10x(2 + 13) = 300$

• $\sf10x(15) = 300$

• $\sf10x = 300 \div 15$

• $\sf x = 20 \div 10$

• $\sf x = 2$

I hope it helps ~
