Name the property that justifies the statement: if 3x = 6 then x = 2.

Step-by-step explanation:

Multiplication Property of Equality: If we multiply both side of an equation by the same non-zero value,the resulting statement is still an equation and it has the same solution set as the original equation.

in the following given question we have the equation 3 x=6; we could seee that in both the sides we have 3 as a common factor. so we'll multiply both sides by to obtain x=2.

hence we get the desired result corresponding to the equation 3x=6.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
