Question

40 POINTS AND BRAINLIEST!! Solve for x in the following equations..

Answer 1

Answer:

a) x = 3

b) x = 10

c) x = 28

Explanation:

a)

$\sf 6x + 3 = 21$

collect term

$\sf 6x = 21-3$

simplify

$\sf 6x = 18$

divide both both sides by 6

$\sf x = 3$

b)

$\sf 15(x - 5) = 75$

distribute

$\sf 15x - 75 = 75$

collect terms

$\sf 15x = 75 + 75$

combine

$\sf 15x = 150$

divide both sides by 15

$\sf x = 10$

c)

$\sf \frac{3}{4} x +5 = 26$

collect like terms

$\sf \frac{3}{4} x = 26-5$

combine

$\sf \frac{3}{4} x = 21$

cross multiply

$\sf x = \frac{ 21 (4)}{3}$

simplify

$\sf x =28$
