7x - 11 = -19 + 3x

Let's first get the x isolated to one side, so subtract 3x from both sides:

4x - 11 = -19

Now add 11 to both sides:

4x = -8

Now to get x by itself, divide 4x by 4, and then divide the other side by 4, leaving:

x = -2

Check your work:
7(-2) - 11 = -19 + 3(-2)
-14 - 11 = -19 - 6
-25 = -25
Yep!

Solve the following system of equations by substitution. Show all steps.
Alinara [238K]

Answer:

Given system of equations:

\begin{cases}f(x)=-x^2+2x+3\\g(x)=-2x+3\end{cases}

To solve by substitution, equate the equations and solve for x:

\begin{aligned}f(x) & = g(x)\\\implies -x^2+2x+3 & = -2x+3\\-x^2+4x & = 0\\x^2-4x & = 0\\x(x-4) & = 0\\\implies x & = 0\\\implies x-4 & = 0 \implies x=4\end{aligned}

Therefore, the x-values of the solution are x = 0 and x = 4.

To find the y-values of the solution, substitute the found values of x into the functions:

f(0)=-(0)^2+2(0)+3=3

g(0)=-2(0)+3=3

f(4)=-(4)^2+2(4)+3=-5

g(4)=-2(4)+3=-5

Therefore, the solutions to the given system of equations are:

(0, 3) and (4, -5)
