3X - 7 = 5
add 7 to each side
3X - 7 + 7 = 5 + 7
3X = 12
divide both sides constants and coefficients by 3
X = 4
check
3(4) - 7 = 5
12 - 7 = 5
5 = 5

How do you solve x over 5 equals 3?
x/5 = 3 Multiply both sides by 5 to find the value of x:- x = 15
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
Just plug in the values for x and y. 4(-1) - 2(5) + (-1)(5) = -19
If y varies inversely as the square of x and y equals 5 when x equals 2.5 what is the value of y when x equals 9?
So 5 = (xy)^2 and x = 2.5. This means that 5 = (2.5y)^2. So sqrt(5)/2.5 = y when x = 2.5. Now if x = 9 then 5 = (9y)^2. So sqrt(5)/9 = y. This means that for any x in this relation y = sqrt(5)/x.
If x equals 5 and y equals 5 then 8x plus 4y equals?
(8 + 4) x 5...
What is the value of 5x -3y when x equals -2 and y equals -4?
5(-2)+(-3)(-4) =-(10)+12 =2
3x7 plus 20-164 equals?
We don't know and can't calculate it, until we're given the value of 'x'.
What is the different between x equals 5 and x equals equals 5?
In C: x = 5 always means assign the value of 5 to x; x == 5 always means compare the value of x with 5.
What is the property of 3x7 plus 2 equals 3x7 plus 3x2?
3(7 + 2) = 3x7 + 3x2 is an example of the distributive law.The distributive law connects multiplication and addition.
What is the value of x in x plus 0 equals 5?
X = 5
If x equals yz find the value for x given that y equals 2 and z equals 5?
x=2*5 x=10
What number sentence shows the distributive property of multiplication 3x7 equals 3x5 plus 3x2 or 3x7x 4 equals 3x 7x4?
3 x 7 = 3 x (5 + 2) And since multiplication is distributive over addition, 3 x (5 + 2) = 3 x 5 + 3 x 2
X2 equals 5 what is the value of x?
if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
What is the value of a -b if a equals 10 and b equals -5?
15
What is the value of x-2 when x equals 5?
3
