The number is 21.
Subtract 6 from each side: 5x = 35Divide each side by 5: x = 7
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.
x=1, y=1
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
The number is 21.
The given expression is x + 6 = 2x + 5. Subtract both sides by x to get: x - x + 6 = 2x - x + 5 6 = x + 5 Subtract both sides by 5 to get: 6 - 5 = x + 5 - 5 x = 1
1 and 2 2 and 3 5 and 6 9 and 10 if you subtract them.
Subtract 6 from each side: 5x = 35Divide each side by 5: x = 7
2x - 6 = x + 5 add 6 and subtract x to both sides; x = 11
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.
First, subtract 1 from 6 turning your next component of the equation to be 5. Then add 5 and 6 to equal 11. Therefore, 6 - 1 + 6 equals 11.
x=1, y=1
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
-2
(6 + y)/ 5= 21 Multiply both sides by 5: 6 + y = 105 Subtract 6 from both sides: y = 99
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
