4x + 3y = -15
2x - 3y = -3
Simultaneous Equations.
Since the coefficient of 'y' is '3' , but of opposite sign, we can add the eq'ns. This will eliminate 'y'
Hence
6x = -18
Divide both sides by '6'
Hence
x = -3
We now substitute this value of 'x' into either eq'n to find 'y' /
Hence
2(-3) -3y = -3
-6 - 3y = -3
-3y = 3
y = -1
Hencethe answer in ( x,y) form is ( -3, -1).

yes
What is the order pair for x plus y equals 15 and 4x plus 3y equals 38?
(1) x+y=15(2) 4x+3y=38From (1) one gets x=15 -y, put into(2)4(15-y)+3y=3860-4y+3y=3860-y=38y=22 then x=15-y=-7(-7,22) is the solution

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.

yes
Solve this equation80 equals 3y plus 2y plus 4 plus 1?
80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15
-3y plus 15-y equals 39?
OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!

What is the order pair for x plus y equals 15 and 4x plus 3y equals 38?
(1) x+y=15(2) 4x+3y=38From (1) one gets x=15 -y, put into(2)4(15-y)+3y=3860-4y+3y=3860-y=38y=22 then x=15-y=-7(-7,22) is the solution
Solve this equation 80 equals 3y plus 2y plus 4 plus 1?
80 = 3y + 2y + 4 + 1 Collect 'like terms'. 80 = 5y + 5 Substract '5' from noth sides 75 = 5y 5y = 75 Divide both sides by '5' y = 15 The answer!!!!!
