Using the elimination method
4x-3y=33
x+4y=14

Step-by-step explanation:

4x-3y=33(1)

x+4y=14(2)

Multiply (2) by 4

4x + 16y = 56(3)

Equation (1) substracted from (3)

4x - 4x + 16y - (-3y) = 56 - 33

16y +3y = 23

19y = 23

y = 23/19

y = 1 4/19

From equation (2)

x + 4y = 14

And y = 23/19

x + 4(23/19) = 14

Multiply each term by 19

19x + 92 = 266

19x = 266 - 92

19x = 174

x = 174/19

x = 9 3/19

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

so, converting firstly the mixed fractions to improper fractions and then "adding".
