2/3 =x
Step-by-step explanation:
f(x) = 3x - 2
Let f(x) =0
0 = 3x-2
Add 2 to each side
2 = 3x-2+2
2 =3x
Divide by 3
2/3 =3x/3
2/3 =x
Answer:
Eva's age is 44 years
Step-by-step explanation:
Let
x ----> Brita's age
y ----> Eva's age
we know that
The sum or their ages 118
so
----> equation A
The difference in age between Brita and her daughter Eva is 30 years
so
----> equation B
Solve the system by elimination
Adds equation A and equation B

<em>Find the value of y</em>
substitute the value of x in any equation

therefore
Eva's age is 44 years
