Soive the equation for the given va
a. -3x + 4y = -12 Solve for y.

Explanation:

−3x + 4y = −12

Add 3x to both sides

−3x + 4y + 3x = −12 + 3x

4y = 3x − 12

Divide both sides by 4

4y / 4 = 3x − 12 / 4

Simplify

-3x+4y=-12

4y=-12+3x

y=3x/4-12/4

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
