Question

Solve for y : 4y+1/3 + 2y+1/2 - 3y-7/5 = 7​

Answer 1

1/ 3 + (-1/2) + (-7/5)+ 4Y -3Y = 47/10

LCM = 30

10 / 30 - -15 / 30 - 42 / 30 + Y = 47 / 10

-47 / 30 + Y = 47 / 10

Y = 47 / 10 + 47 / 30

Y = 141 / 30 + 47 / 30

Y = 188 / 30

Answer 2

Answer:

$4y+ \frac{1}{3} + 2y+ \frac{1}{2} - 3y- \frac{7}{5} = 7 \\ 4y + 2y - 3y + \frac{1}{3} + \frac{1}{2} - \frac{7}{5} = 7 \\ \frac{10y + 10 + 15 - 42}{30} = 7 \\ \frac{10y - 17}{30} = 7 \\ 10y = \frac{7 \times 30}{17} \\ y = \frac{7 \times 30}{17 \times 10} \\ y = \frac{21}{17}$
