5x - (2x + 3) = -3

3x + 3 = -3

      -3     -3

3x = -6

/3      /3

x = -2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

y = 2x + 3

y = 2 (-2) + 3

y = -4 + 3

y = -1

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Can someone please explain how to solve this?<br> 1/2x + 3/2 (x+1) - 1/4 = 5 <br> Thank you!!
Snezhnost [94]

Answer:

x = 1.875

Step-by-step explanation:

<u>Step 1:  Distribute</u>

1/2x + 3/2(x + 1) - 1/4 = 5

1/2x + 3/2x + 3/2 - 1/4 = 5

<u>Step 2:  Combine like terms</u>

4/2x + 6/4 - 1/4 = 5

2x + 5/4 = 5

<u>Step 3:  Subtract 5/4 from both sides</u>

2x + 5/4 - 5/4 = 5 - 5/4

2x = 3.75

<u>Step 4:  Divide both sides by 2</u>

2x / 2 = 3.75 / 2

x = 1.875

Answer:  x = 1.875

Y=2x/a+2b solve for a
mina [271]
Solve for a.

y=2x/a+2b

Multiply both sides by a.

ay=2ab+2x

Add -2ab to both sides.

ay+−2ab=2ab+2x+−2ab

−2ab+ay=2x

Factor out variable a.

a(−2b+y)=2x

Divide both sides by -2b+y.

a(−2b+y) / −2b+y = 2x / −2b+y

a = 2x / −2b+y

Find x and y values that make both y = 2x – 5 Y=-2/3x+ 3 true.
Marysya12 [62]
Set the equations equal to each other since the x will be the same. Get like terms on the same side and solve.

2x-5=-2/3x+3
2x-5+5=-2/3x+3+5
2x=-2/3x+8
2x+2/3x=-2/3x+2/3x+8
2 2/3x=8
8/3x=8
(3/8)8/3x=8(3/8)
x=3

x=3
