If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13

444-351=93

10 minus negative 10 equals 20: 10 - (-10) = 20 or rather 10 + 10 = 20. 10- (minus 10) = 20

x = -2 and y = 1

You cant solve it unless it is an equation. To be an equation it must have an equals sign.

If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3

Yes its on the line.

You'd need another equation to sub in

y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28

Using the quadratic equation formula:- x = 1 +/- the sqrt of 13 = -2.60555 and 4.60555 (to 5 dp).

Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4

Accuracy.

Using the quadratic equation formula the value of x is -8 or 5

It can be solved by using the quadratic equation formula.

By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".

This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8

In that instance, it means that the lines never touch.
