Question

X X 7

What is the solution to the equation 3+ 6 = ?
3
OX= 2
7
OX=3
O x= 3
O x=7

Answer 1

x = 7

Explanation:

Given

`(x)/(3)` +
`(x)/(6)` =
`(7)/(2)` ( multiply through by 6, the LCM of 3,6, 2 to clear the fractions )

2x + x = 21

3x = 21 ( divide both sides by 3 )

x = 7

Answer 2

x=7

Explanation:

x/3 + x/6 = 7/2

Multiply each side by 6 to clear the fractions

6(x/3 + x/6) = 7/2 *6

Distribute

2x +x = 21

Combine like terms

3x = 21

Divide by 3

3x/3 = 21/3

x = 7
