Use absolute value. If both signs are negative you will get a negative number. if both are positive you get positive. if the signs are different, subtract the smaller absolute value from the larger absolute value.

If 15% of 4x is 20 less than x, what is the value of x?
Bess [88]

The sentence "15% of 4x is 20 less than x"

translates to    0.15 • (4x)  = x – 20

Solving that…

    0.15(4x) = x - 20           multiplipy 0.15•4

          0.6x = x - 20           subtract x from both sides

         -0.4x = - 20              divide both sides by -0.4

                x = 50

What are the coordinates of one of the vertices of a rectangle when two sides are given by the lines x - 3y = -8 and 3x + y = 6?
Aleonysh [2.5K]

Answer:

(1, 3)

Step-by-step explanation:

x - 3y = -8

3x + y = 6

Isolate a variable in one of the equations:

y = 6 - 3x

Substitute the value of y into the other equation:

x - 3(6 - 3x) = -8

Use distributive property:

x - 18 + 9x = -8

Combine like terms:

10x - 18 = -8

Isolate the variable:

10x = 10

x = 1

Substitute the value of x into any equation:

3(1) + y = 6

3 + y = 6

Isolate the variable:

y = 3
