First of all, let's agree on what the question is ...
The question is: What's the number for 'x' that makes this statement true ?
Here's how to find it:
11x - 4 = 7x + 16
Add 4 to each side:
11x = 7x + 20
Subtract 7x from each side:
4x = 20
Divide each side by 4:
x = 5
Add your answer:
Earn +20 pts
7x plus 4 equals 3x plus 16 equals?
x=6
7x plus 16 equals 3x plus 4?
7x + 16 = 3x + 4 4x = -12 x = -3
How do you solve 7x plus 2 equals 16?
7x+2-2=16-27x = 147x/7 = 14/7x = 2
What is the y-intercept of the line 8y equals -7x plus 16?
(0,2)
How do you solve 40-7x equals -16?
40 -7x = -16 -7x = -16 -40 -7x = -56 x = 8
-46 equals 3x plus 7x?
-46 = 3x + 7x
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
12-10x equals 7x plus 16 what is x?
-4 = 17x so x = -4/17
2x plus 4x plus 7x equals?
13x
How do you solve this using elimination 7x plus 2y equals 10 and -7x plus y equals -16?
7X + 2Y = 10 - 7X + Y = - 16 -----------------------just add 3Y = - 6 Y = - 2 --------------find X, top equation 7X + 2(- 2) = 10 7X - 4 = 10 7X = 14 X = 2 ------------check both original equations for consistency; top first 7(2) + 2(- 2) = 10 14 - 4 = 10 10 = 10 ------------top checks; now check bottom equation - 7(2) - 2 = - 16 -14 - 2 = - 16 - 16 = - 16 ------------------both check and are then consistent
2x plus 7x equals?
It is 9x
What is the answer to -7x plus 5 equals -9?
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
