3x + 1 = 2x – 3 Why can't you add 3x with 2x? And what should you do for the first step

Mathematics

Tamiku [17]2 years ago
5 0

Answer:

You can’t add 3x with 2x because to get term to the other side of the equal sign, you need to do the inverse (opposite) of the number. Since 3x is positive (basically with a + in the front) you SUBTRACT 3x for it to get to the other side. Which will get u -1x or just -x.

What do you predict the solution for the system 5x-6y=7 and 6x-7y=8 will be ?<br>​
Alenkinab [10]
System of Linear Equations entered :

[1] 5x - 6y = 7
[2] 6x - 7y = 8
Graphic Representation of the Equations :

-6y + 5x = 7 -7y + 6x = 8

Solve equation [2] for the variable x


[2] 6x = 7y + 8

[2] x = 7y/6 + 4/3
// Plug this in for variable x in equation [1]

[1] 5•(7y/6+4/3) - 6y = 7
[1] - y/6 = 1/3
[1] - y = 2
// Solve equation [1] for the variable y


[1] y = - 2
// By now we know this much :

x = 7y/6+4/3
y = -2
// Use the y value to solve for x

x = (7/6)(-2)+4/3 = -1
