What is the solution to the system of equations?

[tex]\[
\begin{array}{l}
y = -5x + 3 \\
y = 1
\end{array}
\][/tex]

A. [tex]\((0.4, 1)\)[/tex]

B. [tex]\((0.8, 1)\)[/tex]

C. [tex]\((1, 0.4)\)[/tex]

D. [tex]\((1, 0.8)\)[/tex]



Answer :

To solve the system of equations:

[tex]\[ \begin{array}{l} y = -5x + 3 \\ y = 1 \end{array} \][/tex]

we start by recognizing that both equations equal [tex]\( y \)[/tex]. Therefore, we can set the expressions for [tex]\( y \)[/tex] from both equations equal to each other:

[tex]\[ -5x + 3 = 1 \][/tex]

Next, we solve for [tex]\( x \)[/tex] step-by-step:

1. Subtract 3 from both sides to isolate the term with [tex]\( x \)[/tex]:

[tex]\[ -5x = 1 - 3 \][/tex]

2. Simplify the right-hand side:

[tex]\[ -5x = -2 \][/tex]

3. Divide both sides by -5 to solve for [tex]\( x \)[/tex]:

[tex]\[ x = \frac{-2}{-5} = 0.4 \][/tex]

Now that we have [tex]\( x = 0.4 \)[/tex], we substitute [tex]\( x \)[/tex] back into either of the original equations to find [tex]\( y \)[/tex]. We use the second equation since it's simpler:

[tex]\[ y = 1 \][/tex]

Thus, the solution to the system of equations is:

[tex]\[ (x, y) = (0.4, 1) \][/tex]

So, the correct answer is:

[tex]\[ (0.4, 1) \][/tex]
