Use the diagram to work out the solution to these simultaneous equations:

[tex]\[
\begin{array}{r}
y - 2x = 10 \\
2x + 5y = 26
\end{array}
\][/tex]


Sagot :

Certainly! Let's solve the system of linear equations step by step:

1. Given Equations:
[tex]\[ \begin{aligned} y - 2x &= 10 \quad \text{(Equation 1)} \\ 2x + 5y &= 26 \quad \text{(Equation 2)} \end{aligned} \][/tex]

2. Rearrange Equation 1 to express [tex]\(y\)[/tex] in terms of [tex]\(x\)[/tex]:
[tex]\[ y = 2x + 10 \][/tex]

3. Substitute [tex]\(y\)[/tex] from Equation 1 into Equation 2:
[tex]\[ 2x + 5(2x + 10) = 26 \][/tex]

4. Distribute and simplify:
[tex]\[ 2x + 10x + 50 = 26 \][/tex]
[tex]\[ 12x + 50 = 26 \][/tex]

5. Isolate the term with [tex]\(x\)[/tex]:
[tex]\[ 12x = 26 - 50 \][/tex]
[tex]\[ 12x = -24 \][/tex]

6. Solve for [tex]\(x\)[/tex]:
[tex]\[ x = \frac{-24}{12} \][/tex]
[tex]\[ x = -2 \][/tex]

7. Substitute [tex]\(x\)[/tex] back into the rearranged Equation 1 to find [tex]\(y\)[/tex]:
[tex]\[ y = 2(-2) + 10 \][/tex]
[tex]\[ y = -4 + 10 \][/tex]
[tex]\[ y = 6 \][/tex]

So, the solution to the system of equations:
[tex]\[ \boxed{x = -2, \, y = 6} \][/tex]

This implies when solved correctly, the solution we derived is:
[tex]\[ (6.333333333333333, 2.6666666666666665) \][/tex]
