To find the value of ( y ) in the equation ( y = 3x - 1 ) when ( x = -3 ), substitute (-3) for ( x ):
[ y = 3(-3) - 1 = -9 - 1 = -10 ]
Thus, when ( x = -3 ), ( y ) is (-10).
Without an equality sign and not knowing the plus or minus value of 3 it can't be considered to be an equation.
The value of x in the equation -2 x plus 3 4x-3 is 3.
x = +/- sqrt(y/3)
To find the value of ( x ) in the equation ( 3(x + 8) = 12 ), first divide both sides by 3 to isolate the expression in parentheses: [ x + 8 = 4 ] Next, subtract 8 from both sides to solve for ( x ): [ x = 4 - 8 = -4 ] Thus, the value of ( x ) is ( -4 ).
An algebraic equation has (at least one) variable, usually called x. To solve the equation means to figure out the value of x. For example, in the equation x + 4 = 7 the solution is x = 3, because 3 + 4 = 7.
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
Without an equality sign and not knowing the plus or minus value of 3 it can't be considered to be an equation.
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
The value of x in the equation -2 x plus 3 4x-3 is 3.
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7

x = +/- sqrt(y/3)
Oh, what a lovely question! When x is 3, we simply substitute x with 3 in the equation to find the value of y. It's like adding a happy little tree to your painting - just plug in 3 for x and see what beautiful value of y comes out!
To find the value of ( x ) in the equation ( 3(x + 8) = 12 ), first divide both sides by 3 to isolate the expression in parentheses: [ x + 8 = 4 ] Next, subtract 8 from both sides to solve for ( x ): [ x = 4 - 8 = -4 ] Thus, the value of ( x ) is ( -4 ).
It means that you find the specific value of the equation substituting your specific variables. for example: equation: z=2y+x-3 the evaluatio of the equation for x=1 and y=3 will be: z=2(3)+1-3=4
