15+3x-7=6x+8-3x solve the linear equation x=

The given expression has NO SOLUTION.

Step-by-step explanation:

Here, the given expression is  -15 + 3 x -7 = 6 x +  8- 3 x

Solving this for the value of x, we get:

-15 + 3 x -7 = 6 x +  8 - 3 x  

⇒ - 22 + 3 x  =  3 x + 8

or, -22 = 8

This given us A CONTRADICTION as -22 ≠ 8

Hence, the given expression has NO SOLUTION.

is means division by fractions

step-by-step explanation:

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
