Question

Solve for x.
6
х
12
15
X=
units

Answer 1

x = 4

Explanation:

If a line is parallel to a side of the triangle and intersects the other 2 sides then it divides those sides proportionally, that is

`(2)/(4)` =
`(x-1)/(6)` ( cross- multiply )

4(x - 1) = 12 ( divide both sides by 4 )

x - 1 = 3 ( add 1 to both sides )

x = 4

Answer 2

Multiply the numbers all together
