Why is 3x over 4 plus x equal to 7x over 4?
3x/4 + x = 7x/4 because 4x/4 = x 3x/4 + 4x/4 = 7x/4
What is the answer for 3x plus 4-7x equals 5-4x plus 2?
3x+4-7x=5-4x+2 -4x+4=7-4x Adding 4x to each side yields: 4=7, which is not true, so there is no answer (a null set)
How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
What is the answer to 7x-9 equals 3x plus 5?
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
-3x plus 2 equals -7x-22?
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
Why is 3x over 4 plus x equal to 7x over 4?
3x/4 + x = 7x/4 because 4x/4 = x 3x/4 + 4x/4 = 7x/4
7x plus 16 equals 3x plus 4?
7x + 16 = 3x + 4 4x = -12 x = -3
What is the answer for 3x plus 4-7x equals 5-4x plus 2?
3x+4-7x=5-4x+2 -4x+4=7-4x Adding 4x to each side yields: 4=7, which is not true, so there is no answer (a null set)

IF 7x -4 equals 3x plus 36 what is x?
7x-4 = 3x+36Add 4, it cancels out.. So,7x = 3x+40Now subtract 3x from 7x..4x = 40..40 divided by 4 is 10So, X= 10
What is the answer to 7x-9 equals 3x plus 5?
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
7x-3 equals 3x plus 8?
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
How do you solve this eqation 7x plus 2 equals 3x-2 what is the value of x?
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
-3x plus 2 equals -7x-22?
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
What is -3x plus 2 equals -7x-22?
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6
What does 7x-3x equals?

How do you solve 7x plus 4 equals 3x plus 7?
(7x + 4) = (3x + 7) Subtract (3x + 4) from both sides of the equation. (7x + 4) - 3x - 4 = (3x + 7) - 3x - 4 4x = 3 x = 3/4 Check: (7x + 4) = 7 (3/4) + 4 = (21/4) + 4 = (21/4) + (16/4) = 37/4 (3x + 7) = 3 (3/4) + 7 = (9/4) + 7 = (9/4) + (28/4) = 37/4 Yay.
