Liula [17]3 years ago
4 0

The answer 6x - 2y = 5

Step-by-step explanation:

The general formula of linear equations is y = mx + c

where m is the slope

so when we put this in the general form, it will be

-2y = -6x + 5

y = 3x - 5/2

and so the slope is 3

Subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x.
kicyunya [14]

Simplified value of  subtraction of 7x+27x+2 from -5x^2-2x−5x 2 −2x. is -10x^{2} -38x-2.

Given Expressions  7x+27x+2 and  -5x^2-2x−5x 2 −2x.

Expressions refers to the combination of numbers, variables and symbols. It represents the relationship between variables. They are solved for finding out the value of variables. It is mainly not in equal to form. Subtraction is possible when subtracting the coefficients of same variable.

We have to subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x. and to do this we need to first solve the expressions itself.

7x+27x+2=34x+2------------------1

-5x^{2} -2x-5x^{2} -2x=-10x^{2} -7x-2x--------------------2

Now subtract 1 from 2

=-10x^{2} -7x-2x-34x+2

=-10x^{2} -38x-2.

Hence the simplified value of subtraction is -10x^{2} -38x-2.

Solve the system of linear equations by substitution. y=2x+5 and y=3x-1
Doss [256]
Plug in the second equation into the first equation for y.
y = 2x + 5 \\ y = 3x - 1 \\ 3x - 1 = 2x + 5
Now put the variable on one side and constants on the other
3x - 1  + 1 - 2x = 2x - 2x + 5 + 1 \\ x = 6
Now plug that back into one of the original equations
y = 2x + 5 \\ y = 2(6) + 5 \\ y = 12 + 5 \\ y = 17
So now you know
x = 6 \\ y = 17
Its always a good idea to check
17 = 2(6) + 5 \\ 17 = 17 \\ 17 = 3(6) - 1 \\ 17 = 17
