Answer: x = 27
Explanation:
To solve this, first insert 4 for y:
3x - 4 * 4 = 65
Next, multiply the numbers:
3x - 4 * 4 = 65
3x - 16 = 65
Next, move the constant to the right and change its sign:
3x - 16 = 65
3x = 65 + 15
Next, add the numbers:
3x = 65 + 16
3x = 81
Finally, divide both sides of the equation by 3:
3x = 81
3x ÷ 3 = 81 ÷ 3
(Any expression divided by itself equals 1)
3x ÷ 3 = 81 ÷ 3
x = 81 ÷ 3
x = 81 ÷ 3
x = 27
