It is an equation and the value of x is 4
If you mean: 2x+5+3x = 25 then the value of x works out as 4
If: -8x+4 = 36 then the value of x works out as -4 Check: -8*(-4)+4 = 36
If x = 4 and y = 2 then 4(5+2) = 28
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2
3x + y = 4x + y = 0solve for yy = -3x +4y = -xsubstitute y = -x into y = -3x +4, so the result is: -x = -3x +4solve for x-1x = -3x +4+3x +3x2x = 4--------2x = 2then plug the x-value into one of the bolded equations and solve for y.I chosey = -xy = -(2)y = -2so the final answer is the ordered pair (2, -2)
It depends on the value of X If we assume that the value of X is 22, then 22 + 4 = 26
x = 4
-1
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
It is 2.
X = 4
x=4
It is an equation and the value of x is 1
x=4
7
Exactly (2y + 4) .
