Two equations two unknowns
1. 3a + 6s = 60
2. 5a + 3s = 44
solve for a in 1, a = (60 - 6s)/3 = 20 - 2s
substitute into 2
5(20 - 2s) + 3s = 44
solve for s
s = 8
substitute in 1
a = 4
Answer:
No solutions
Step-by-step explanation:
Given two linear equations in slope-intercept form with same slopes but different y-intercepts.
To find the number of solutions,we can get for this system of equations.
Solution:
The slopes of two lines say and are related as:
only when the lines are parallel or if both are equations of same line.
And since the y-intercept of given lines are different, so we can conclude that the equations are of two different lines that are parallel to each other.
Thus the given system of linear equations with same slope but different y-intercepts will have no solution as the given lines are parallel to each other and hence would never meet.
Answer:
-36 • (22u + 1)
Pulling out like terms :
2.1 Pull out like factors :
-74u - 5 = -1 • (74u + 5)
Equation at the end of step 2 :
(6 • (58u + 1)) - -6 • (74u + 5)
Step 3 :
Equation at the end of step 3 :
6 • (58u + 1) - -6 • (74u + 5)
Step 4 :
Pulling out like terms :
4.1 Pull out 6
Note that -6 =(-1)• 6
After pulling out, we are left with :
6 • ( (-1) * (58u+1) +( (-1) * (74u+5) ))
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
-132u - 6 = -6 • (22u + 1)
Final result :
-36 • (22u + 1)
