Help me find the values of x

1. 2x+1=9

2. 4x+3=19

3. 3x-2=7

Answers

1.) x = 4
2.)x = 4
3.)x= 3
1. x = 42. x = 43. x = 3

____________________________________________________

If there's addition, use subtraction to find the value.If there's subtraction, use addition to find the value.

x(y) means to multiply x with y

____________________________________________________

1. In the first problem, we need to subtract 1 from 9 since there is an addition:

9 – 1 = 8

Next, divide 8 by 2, and we get:

8 ÷ 2 = 4

This means that x = 4

Finally, check the answer by:

2(4) + 1 = 9

2. In the second problem, we need to subtract 3 from 19 since there is an addition:

19 – 3 = 16

Next, divide 16 by 4, and we get:

16 ÷ 4 = 4

This means that x = 4

Finally, check the answer by:

4(4) + 3 = 19

3. In the third problem, we need to add 2 with 7 since there is subtraction:

2 + 7 = 9

Next, divide 9 by 3, and we get:

9 ÷ 3 = 3

This means that x = 3

Finally, check the answer by:

3(3) – 2 = 7

How do you multiply 2 1/4*4/7
Help explain it please

Answers

Conversion a mixed number 2*1/4

to a improper fraction: 2*1/4 = (2* 1)/4

= (2( 4 )+ 1)/4 = (8 + 1)/4 = 9/4

To find a new numerator:

a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally

(2 * 4)/4 = 8/4

b) Add the answer from the previous step 8 to the numerator 1. New numerator is 8 + 1 = 9

c) Write a previous answer (new numerator 9) over the denominator 4.

Two and one quarter is nine quarters.

Conversion a mixed number

1*4/7

to a improper fraction:

1*4/7 = 1*4/7 = 1 *( 7 + 4) / 7= (7 + 4) / 7= 11 / 7

To find a new numerator:

a) Multiply the whole number 1 by the denominator 7. Whole number 1 equally 1 * 7/ 7 = 7/7

b) Add the answer from the previous step 7 to the numerator 4. New numerator is 7 + 4 = 11

c) Write a previous answer (new numerator 11) over the denominator 7.

Applying the fractions formula for multiplication,

=9/4 x 4/7 (A Times symbol beside each number)

=36/28

Simplifying 36/28, the answer is
