Question Find the value of $b$ when $b=3-2a$ and $a=4$ .

Studdy Solution

STEP 1

Assumptions1. The value of $a$ is given as4. The equation for $b$ is given as $b=3-a$

STEP 2

We can find the value of $b$ by substituting the given value of $a$ into the equation for $b$ .
$b = -2a$

STEP 3

Substitute $a =$ into the equation.
$b =3 -2 \times$

STEP 4

Perform the multiplication.
$b =3 -8$

STEP 5

Subtract8 from3 to find the value of $b$ .
$b = -5$ So, the value of $b$ when $a=4$ and $b=3-2a$ is $-5$ .

Question Find the value of bbb when b=3−2ab=3-2ab=3−2a and a=4a=4a=4.

Studdy Solution

STEP 1

Assumptions1. The value of aaa is given as4. The equation for bbb is given as b=3−ab=3-ab=3−a

STEP 2

We can find the value of bbb by substituting the given value of aaa into the equation for bbb.b=−2ab = -2ab=−2a

STEP 3

Substitute a=a =a= into the equation.b=3−2×b =3 -2 \timesb=3−2×

STEP 4

Perform the multiplication.b=3−8b =3 -8b=3−8

STEP 5

Subtract8 from3 to find the value of bbb.b=−5b = -5b=−5So, the value of bbb when a=4a=4a=4 and b=3−2ab=3-2ab=3−2a is −5-5−5.
