Answer:
1.  Substitute y = -3x +4 for y in the first equation
2.  Combine like terms and isolate x
3.  Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1.  Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2.  Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10  Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
 y = -3x +4 
y = -3(2) +4
y = -6+4
y=-2
(2,-2)
 
        
             
        
        
        
Answer:
$8.60
Step-by-step explanation:
Let’s find the cost for each item
Apples: 2.5 x 1.30 = 3.25
Grapes: 2.5 x 1.65 = 4.125
Bananas: 2.5 x 0.49 = 1.225
Now we will add all the costs which will give use our total!
3.25 + 4.125 + 1.225 = 8.6
So the answer will be $8.60
