Question

x/10+70-x/2=19
solve the following equation for given variable
​

Answer 1

Answer:

x = 127.5

Step-by-step explanation:

$\frac{x}{10} + 70 - \frac{x}{2} = 19 \\ \frac{x + 700 - 5x}{10} = 19 \\ 700 - 4x = 19 \times 10 \\ 700 - 4x = 190 \\ - 4x = 190 - 700 \\ - 4x = - 510 \\ x = \frac{ - 510}{ - 4} \\ x = 127.5$

Answer 2

Answer:

combining like terms,

x\10-x\2+70=19

LCM,

x-5x\10=19-70

-4x\10=-51

-2x\5=-51

-2x=-51×5

-2x=- 255

x=-255\-2

x=127.5
