What is -15 plus n equals -9?
It is an equation and the value of n is 6
What is 6d plus 1 equals 15 -1d?
It is an equation and the value of d is 2
What is the value is ywhen x equals 15?
There's no way to calculate it without an equation that describes the relationship between 'x' and 'y'.
Is 8 equals 15-7 a math equation?
8 = 15 - 7 8 = 8 Yes it is an equation.
What is 15-6 equals 9?
This is called an equation....

What is 6d plus 1 equals 15 -1d?
It is an equation and the value of d is 2
What is the equation for 15 equals 5b?
15 = 5b

3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
What is the substiution eqaution for x plus y equals 15 and 4x plus 3y equals 38?
x + y = 154x + 3y = 38from the first equation, y = 15-xsubstitute this value in the second equation as follows:4x + 3(15-x)= 384x + 45 - 3x = 38x + 45 = 38x = 38 - 45so, x = -7substitute this value to solve for y:y = 15 -xy = 15-(-7)y = 22
9 times z equals 135 what is z?
To find the value of z, set up the equation: 9z = 135 (then divide both sides of the equation by 9) z = 15
Is 8 equals 15-7 a math equation?
8 = 15 - 7 8 = 8 Yes it is an equation.
What is 15-6 equals 9?
This is called an equation....
What is the answer to the equation 3c-15 equals 17-c?
The value of 'c' that makes the equation a true statement is the answer.Here's how to find it:Write the equation:3c - 15 = 17 - cAdd 'c' to each side:4c - 15 = 17Add 15 to each side:4c = 32Divide each side by 4:c = 8
What is the answer to the equation 3C-15 for C equals 21?
This does not sound like an equation. This sounds like evaluating an algebraic expression. 3C means 3 times the value of C (which you have given as 21) then subtract 15. 3 x 21 - 15 = 48
What is the y-intercept of the line given by the equation y equals -2x 15?
The answer depends on the sign preceding the value 15 (which is not given in the question). If y = -2x+15 then (0,15) if y= -2x-15 then (0,-15)
