Eq 1: + y= 5
Eq 2: x = y + 1
substitute y + 1 for x in equqtion 1
y+1 + y = 5
2y + 1 = 5
2 y = 4
y = 2
substitute 2 for y in eq 2

What is the answer to this problem If 1 plus 5 equals 12 and 2 plus 10 equals 24 and 3 plus 15 equals 36 then 5 plus 25 equals what?
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.

-5x plus y equals -5 -4x plus 2y equals 2?
I assume that you mean 5x + y = -5 -4x + 2y = 2 Cancel the 2s from the second equation -2x + y = 1 therefore y = 1+2x Substitute into first equation 5x + 1 + 2x = -5 7x = -6 x = -6/7 Substitute into second equation to find that y = -5/7.
12 plus 5n equals if n is 5?

Is point 1 2 represented by the equation x plus 2y equals 5?
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.
