Answer: x=15
Step-by-step explanation:
Equation: 107=(9x-115)+(4x+27)
Step 1: 9x+4x-115+27=107
Step 2: 13x-115+27=107
Step 3: 13x-88=107
Step 4: 13x-88+88=107+88
Step 5: 13x=195
Step 6: 13x/13=195/13
x=15
Answer:63
Step-by-step explanation:
63/7+25=34
D because If she uses any other loan she might she will owe money
Answer:
the answer is 41.5
Step-by-step explanation:
-80=-2x+3
-80-3=-2x
-83=-2x
41.5=x
If we sum these 2 equations we will get:
2y = 0 -> y = 0
Now we replace y=0 in any of 2 equations to solve for x:
0 = 3.5x - 3.5
3.5 = 3.5x
x=1
That means that there is only 1 solution and that one is (1,0)
