It is an equation and the value of n is 6
It is an equation and the value of d is 2
There's no way to calculate it without an equation that describes the relationship between 'x' and 'y'.
8 = 15 - 7 8 = 8 Yes it is an equation.

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.

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
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)
