4x - 6 = x + 9
4x - x = 9 + 6
3x = 15
x = 15/3
x = 5
==============
4 - 7x = 1 - 6x
4 - 1 = -6x + 7x
3 = x
==============
-4x - 3 = -6x + 9
-4x + 6x = 9 + 3
2x = 12
x = 12/2
x = 6
==============
41 - 2x = 2 + x
41 - 2 = x + 2x
39 = 3x
39/3 = x
13 = x
===============
6(2 + y) = 3(3-y)
12 + 6y = 9 - 3y
6y + 3y = 9 - 12
9y = - 3
y = -3/9
y = -1/3
==============
4x = 2(x - 5) - 2
4x = 2x - 10 - 2
4x - 2x = -10 - 2
2x = -12
x = -12/2
x = -6
===============
6x - 9x - 4 = -2x - 2
-3x - 4 = -2x - 2
-4 + 2 = -2x + 3x
-2 = x
==============
-2(2x + 3) = -4(x + 1) - 2
-4x - 6 = -4x - 4 - 2
-4x - 6 = -4x - 6
infinite solutions
================
3 + 6x = 9 - 6x
3 - 9 = -6x - 6x
-6 = -12x
-6/-12 = x
1/2 = x
==============
-9x + 6 = -x + 4
6 - 4 = -x + 9x
2 = 8x
2/8 = x
1/4 = x

I hope I read these correctly....not that easy...u got weird looking x's and ur 4's can almost pass for 6's

Ariana plans to use $260 less than three-fourths of savings to buy a car. If the purchase price of the car is 9,340, how much do
tangare [24]

She has $12,488 in savings

Step-by-step explanation:

Ariana plans to use $260 less than three-fourths of savings to buy a car.

If the purchase price of the car is 9,340, we need to find how much

she has in savings

To find the savings

  • Assume that she has $x in savings
  • Write an equation of x
  • Solve the equation to find x

∵ She has $x in savings

∵ She plans to use $260 less than three-fourths of savings

- Three-fourths means \frac{3}{4} and less than means subtract

∴ She plans to use \frac{3}{4} x - 26

∵ The purchase price of the car is 9,340

- Equate the expression of x by 9,340

∴ \frac{3}{4} x - 26 = 9,340

Now let us solve the equation

∵ \frac{3}{4} x - 26 = 9,340

- Add 26 to both sides

∴ \frac{3}{4} x = 9,366

- Divide both sides by \frac{3}{4}

∴ x = $12,488

She has $12,488 in savings
