Simplify both sides of the equation

3(x-4)+12(x-9)=4x+13

Distribute

(3)(x)+(3)(-4)+(12)(x)+(12)(-9)=4x+13

3x+-12+12x+-108=4x+13

Combine like terms

15x+-120=4x+13

15x-120=4x+13

Subtract 4 from both sides

15x-120-4x=4x+13-4x

11x-120=13

Add 120 to both sides

11x-120+120=13+120

11x=133

Divide both sides by 11

11x/11=133/11

x=133/11

or x= 12 1/11


I hope that's help !

I Nisa buy dollars worth of stock and gained $25 per year Kevin bad for hundred dollars worth of stock in the last $35 per year
alisha [4.7K]

Answer: x= 5 years and y = $225

Step-by-step explanation:

Since we have given that

Amount Nisa gained per year = $25

Amount Kevin lost per year = $35

According to question,

y=100+25x\\\\and\\\\y=400-35x

so, it becomes,

100+25x=400-35x\\\\25x+35x=400-100\\\\60x=300\\\\x=\frac{300}{60}\\\\x=5

so, For x= 5 years,

Their income of Nisa and loss of Kevin will be

y=100+25x\\\\y=100+25\times 5\\\\y=100+125\\\\y=\$225
