Answer:
= − 3
Step-by-step explanation:
15−2x=−7x
− 2 + 15 = −7
−2+15−15=−7−15
−2=−7−15
so 1 . you rearrange the terms
2. subtract 15 from both sides
3 simpfly subtract the number
Answer:
You will move - 2x to the other side to gather factores x with considering change the sign because the changing in side so it will became
15=2x-7x
15=-5x
To find x you need to remove its variable -5 and that happen by devided it just basic algebra
X=15/-5
X=-3

Answer:
107.20 euros.
Step-by-step explanation:
Let the amount she had initially be x euros.
Then we have the equation:
x - 0.40x - 0.35x = 26.80
x - 0.75x = 26.80
0.25x = 25.80
Multiply both sides by 4:-
x = 107.20 euros.
