Solve this equation 3/5(x-10)=18-4x-1 combine like terms that are on the same side of the equation
hjlf

Answer:

x=5

Step-by-step explanation:

3/5(x-10)=18-4x-1

3/5x-30/5=18-4x-1

3/5x-6=18-4x-1

+6 +6

3/5x=23-4x

+4x +4x

4 3/5x=23

23/5x=23

23/5 divide , so you actually multiply both sides by the reciprocal 5/23

x=5

What is the solution to this system of linear equations 3x 2y 14 5x y 32
Leya [2.2K]

After simplification, the solution of this system of linear equation is (3.85, 12.75).

In the given question we have to find the solution to this system of linear equations 3x-2y=14 or 5x+y=32.

The given system of linear equations is:

3x-2y=14.......................(1)

5x+y=32.......................(2)

Multiply equation 2 by 2, we get

10x+2y=64.......................(3)

Add equation 3 by 1, we get

10x+2y+3x-2y=64-14

13x=50

Divide by 13 on both side, we get

x=3.85

Now put the value of x in equation 2

5(3.85)+y=32

19.25+y=32

Subtract 19.25 on both side, we get

y=12.75

So, the solution of this system of equation is (3.85, 12.75).

Solve this for n by dividing 7.5 km into 45 km:

n = 6

There were 6 runners.
