- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y + 5x = 1
5y - x = 5
<u>Step 2: Rewrite Systems</u>
y + 5x = 1
- Subtract 5x on both sides:                    y = 1 - 5x
<u>Step 3: Redefine Systems</u>
y = 1 - 5x
5y - x = 5
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitution in <em>y</em>:                      5(1 - 5x) - x = 5
- Distribute 5:                             5 - 25x - x = 5
- Combine like terms:                5 - 26x = 5
- Isolate <em>x</em> term:                          -26x = 0
- Isolate <em>x</em>:                                   x = 0
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation:                    5y - x = 5
- Substitute in <em>x</em>:                       5y - 0 = 5
- Subtract:                                 5y = 5
- Isolate <em>y</em>:                                 y = 1
 
        
             
        
        
        
 
 
it's a right angled triangle so we will use hypotenuse formula to get the value of x
hypotenuse formula = a² + b² = c²
a = side of the triangle
b = base of traingle
c = hypotenuse ( can be written as h too)
and the formula can also be written as.
c² = a² + b²
<em><u>therefore</u></em><em><u>,</u></em><em><u> </u></em><em><u>x </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>2</u></em><em><u>.</u></em><em><u>1</u></em>
