Fractional Equations Help with steps

Answer 1

Answer:

see explanation

Step-by-step explanation:

(e)

$\frac{2x-1}{3}$ - $\frac{3x-1}{4}$ = 1

Multiply through by 12 to clear the fractions

4(2x - 1) - 3(3x - 1) = 12 ← distribute parenthesis and simplify

8x - 4 - 9x + 3 = 12

- x - 1 = 12 ( add 1 to both sides )

- x = 13 ( multiply both sides by - 1 )

x = - 13

---------------------------------------------------------------

(f)

$\frac{3m}{4}$ - 5 = 24 ( add 5 to both sides )

$\frac{3m}{4}$ = 29 ( multiply both sides by 4 )

3m = 116 ( divide both sides by 3 )

m = $\frac{116}{3}$

--------------------------------------------------------------

(g)

$\frac{5(y+2)}{2}$ - $\frac{4(y+1)}{3}$ = 3

Multiply through by 6 to clear the fractions

15(y + 2) - 8(y + 1) = 18 ← distribute parenthesis and simplify

15y + 30 - 8y - 8 = 18

7y + 22 = 18 ( subtract 22 from both sides )

7y = - 4 ( divide both sides by 7 )

y = - $\frac{4}{7}$
