Question

Solve for x. 6 х 12 15 X= units

Answer 1

Multiply the numbers all together

Answer 2

Answer:

x = 4

Step-by-step 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

$\frac{2}{4}$ = $\frac{x-1}{6}$ ( cross- multiply )

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

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

x = 4
