It is an equation and the value of n is 6
It is an equation and the value of d is 2
To solve the equation ( m - 15 = 5 ), you can add 15 to both sides. This gives you ( m = 5 + 15 ), which simplifies to ( m = 20 ). Therefore, the value of ( m ) that makes the equation true is 20.
There's no way to calculate it without an equation that describes the relationship between 'x' and 'y'.
An equation that contains at least one variable is (2x + 5 = 15). In this equation, (x) is the variable, and the equation states that when you multiply (x) by 2 and add 5, the result equals 15. Solving for (x) will allow you to find its value.

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
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
To find the value of z, set up the equation: 9z = 135 (then divide both sides of the equation by 9) z = 15
8 = 15 - 7 8 = 8 Yes it is an equation.
This is called an equation....
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
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
