Answer:
<em>6.5</em>
Step-by-step explanation:
To perform this kind of exercise, it is necessary to replace the value indicated in each variable each time you find the variable in the equation.
If j=0.5 and k=0.25, replace the value of each variable.
now perform the indicated operations
Step 1: Y is equal to so where ever you see a y in the equation 3x - 4y = -5 replace it with
3x - 4() = -5
Now all your variables are x and you can solve for x
Step 2: Distribute for to the numbers in the parentheses
3x - 3x - 8 = -5
Step 3: Combine like terms
0x - 8 = -5
0x = 3
Step 4: Isolate x
0x/0 = 3/0
3/0 is undefined
^^^ This means that there is no answer
If you look at the graph below you can see that these lines are parallel and therefore have no intersection point
Hope this helped!
