Answer:
whitch question
Step-by-step explanation:
Hmmm..... let us try again...but this time with a different strategy,.... by the graph method.
The system is
3x + 4y =96
2x + 5y = 99.
We find solutions of each system and then plot them on a graph.
Solutions for equation 1 = (2, 22.5) and (30, 0)
Solutions for equation 2 = (49.5 , 0) and (1, 19.4)
Now, we plot both the equations on a graph paper and note its intersecting point.
Experimentally, we find the intersecting point is (12,15)
Thus, the solution for the system is x = 12 , y = 15.
Thus, we arrive at the conclusion 1 shirt costs 12$
1 cap costs 15$
Answer:
x = -3/10
Step-by-step explanation:
1/2(2x - 1) = -1/5 -3/5
Combine like terms
1/2(2x - 1) = -4/5
Multiply each side by 2
2* 1/2(2x - 1) = -4/5*2
2x-1 = -8/5
Add 1 to each side
2x-1+1 = -8/5 +1
2x = -8/5+5/5
2x = -3/5
Divide by 2
2x/2 = -3/5 * 1/2
x = -3/10
