If 2x-3y equals -1 and 3x plus 2y equals 31 find the values of x and y?

2x - 3y = -1
3x + 2y = 31
eqn(1) * 2: 4x - 6y = -2
eqn(2) * 3: 9x + 6y = 93
Add the two: 13x = 91
Divide both sides by 13: x = 7
Substitute this value of x into eqn(1): 14 - 3y = -1
Add 3y to bot sides: 14 = -1 + 3y
Add 1 to both sides: 15 = 3y
Divide both sides by 3: 5 = y
So the solution is x = 7, y = 5

A plus b plus c plus d plus e equals 30 where c plus e equals 14 and d equals b plus 1 and a equals 2b-1 and a plus c equals 10 find values of letters?
a+b+c+d+e = 30 (i) c+e = 14 (ii) d+b = 1 (iii) a = 2b-1 (iv) a+c = 10 (v) By (i)-(ii)-(iii): a = 15 then, by (iv): b = 8 and by (v): c = -5 Also, b = 8 so by (iii): d = -7 and then by (i), e = 19
Why are the equations w minus x plus x equals w and w plus x minus x equals w called Identities?
They are identities because they are true for ALL values of w and x.
1 plus 1 equals 2 plus 2 equals 4 plus 4 equals 8 plus 8 equals 16 plus 16 equals 32 plus 32 equals 64 plus 64 equals 128 plus 128 equals 256 plus 256 equals 512 plus 512 equals 1024 plus 1024 equals?

What is the slope of line with the equation 2x 3y plus 6 equals 0?
Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.
Where do the curves of y equals 4x squared -2x -1 and y equals -2x squared plus 3x plus 5 intersect?
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.
