To solve for x, let's first simplify the equation:
20(2x - 8) = 440
First, we will distribute 20 to the terms inside the parentheses:
40x - 160 = 440
Next, let's isolate the variable x by adding 160 to both sides of the equation:
40x = 440 + 160
40x = 600
Finally, we will divide both sides of the equation by 40:
x = 600/40
x = 15
Therefore, the solution for x is 15.

Solve for x
0.72 = 0.4 (x + 1.4)
0.72 = 0.4 (x + 1.4)
To solve for x, we will first distribute 0.4 to the terms inside the parentheses:
0.72 = 0.4x + 0.4(1.4)
Next, we will simplify the expression:
0.72 = 0.4x + 0.56
To isolate the variable x, we will subtract 0.56 from both sides of the equation:
0.72 - 0.56 = 0.4x + 0.56 - 0.56
0.16 = 0.4x
Finally, we will divide both sides of the equation by 0.4:
0.16/0.4 = (0.4x)/0.4
0.4 = x
Therefore, the solution for x is 0.4.
0.72 = 0.4x + 0.4(1.4)
Next, we will simplify the expression:
0.72 = 0.4x + 0.56
To isolate the variable x, we will subtract 0.56 from both sides of the equation:
0.72 - 0.56 = 0.4x + 0.56 - 0.56
0.16 = 0.4x
Finally, we will divide both sides of the equation by 0.4:
0.16/0.4 = (0.4x)/0.4
0.4 = x
Therefore, the solution for x is 0.4.
Solve for x
2(1.5x - 7) = 6
2(1.5x - 7) = 6
To solve for x, let's start by distributing 2 to the terms inside the parentheses:
2(1.5x - 7) = 6
2 * 1.5x - 2 * 7 = 6
3x - 14 = 6
Next, we want to isolate the variable x. To do that, we'll add 14 to both sides of the equation:
3x - 14 + 14 = 6 + 14
3x = 20
Finally, divide both sides of the equation by 3 to solve for x:
3x/3 = 20/3
x = 20/3
Therefore, the solution for x is x = 20/3.
2(1.5x - 7) = 6
2 * 1.5x - 2 * 7 = 6
3x - 14 = 6
Next, we want to isolate the variable x. To do that, we'll add 14 to both sides of the equation:
3x - 14 + 14 = 6 + 14
3x = 20
Finally, divide both sides of the equation by 3 to solve for x:
3x/3 = 20/3
x = 20/3
Therefore, the solution for x is x = 20/3.

20 รท 3 = 6.6667 (rounded to four decimal places)
Therefore, 20/3 in decimal form is approximately 6.6667.
Solve for x
5x - 2x + 4 = -5
5x - 2x + 4 = -5
To solve for x, let's start by combining like terms on the left side of the equation:
