Question

algebraic expression. . .
solve..
a)
$\frac{x}{3} - 2 = \frac{x}{4 } + 5$
b)
$\frac{x}{5} + 3 = \frac{x}{6} + 12$
c)
$\frac{3}{8} (x - 5) = 9 - 2x$
​

Answer 1

Solution:

(A) x/3 - 2 = x/4 + 5

• x/3 - x/4 = 5 + 2
• (4x - 3x)/12 = 7
• 4x - 3x = 84
• x = 84

(B) x/5 + 3 = x/6 + 12

• x/5 - x/6 = 12 - 3
• (6x - 5x)/30 = 9
• 6x - 5x = 270
• x = 270

(C) 3/8 (x - 5) = 9 -2x

• (3x - 15)/8 = 9 - 2x
• 3x - 15 = 8 (9 - 2x)
• 3x - 15 = 72 - 16x
• 3x + 16x = 72 + 15
• 19x = 87
• x = 87/19
