Question

Solve the question by the system of linear equation by substitution method
5x - 3 = 16, 3x +2y =4​

Answer 1

Answer:

x=44 and y= -28/19.

Step-by-step explanation:

5x-3y=16-----(i)

3x+2y=4-----(ii)

from equation (i)

5x-3y=16

x=16+3y ÷5

substitute value of x in equation (ii)

3x+2y=4

=3×16+3y÷5+2y=4

=48+9y+10y÷5=4

=48+19y=20

=19y= -28

=y= -28/19

substitute value of y in equation (i)

5x -3y=16

5x-3×-28/19-16=0

5x+84/19-16/1=0

5x-220÷19=0

5x=220

x=220/5

x=44.
