substitution
y = 7x-26 (1)
y = 4x-11 (2)
1⇒2
7x-26=4x-11
3x=15
x=5
y = 7(5)-26
y = 9
point (5,9)
Let's assume 42391.29 is divided into x parts to get 1988.83
so, we can also write as
now, we can solve for x
we can simplify it
and we get
so,
.............Answer
To write in slope intercept form solve the equation for y:
4x + 3y =15
Subtract 4x from both sides:
3y = -4x +15
Now get Y by itself by divide all terms by 3:
y = -4/3x + 5
Answer: is 2.11
explanation: We have to do 12.66/6=2.11
we have to divide
