An expression is an equation WITHOUT the equal sign so for example 3x-4n or 99x/2
Whereas, an equation DOES have an equal sign ( just remember "equa" is equal)
So, 1=z and x=1 aren't expressions

Need help with this problem
alexandr1967 [171]

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

\frac{20}{20+8} = \frac{3x}{4x+2}, that is

\frac{20}{28} = \frac{3x}{4x+2} ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10
