3x + 7 = -4x + 28 implies 7x + 7 = 28
x=-5
x = 5
4x plus 7 plus 3x equals 19 plus xx = 2
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
3x + 7 = -4x + 28 implies 7x + 7 = 28
x=-5
x = 5
3x - 7 + 4x = 28 7x - 7 = 28 I added 4x and 3x to get 7x 7x = 35 I subtracted 7 from both sides x = 5 I divided by 7 on both sides
The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
4x plus 7 plus 3x equals 19 plus xx = 2
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
3x+7=4x 7=4x-3x 7=x
3x+7=37 -7 -7 3x=30 /3 /3 x=10
3x + 2y = 7
In the equation 3x plus 7 equals 13, x is equal to 2.
