Question

solve using substitution method, 4x+3y=2100 and 5x+2y=1750

Answer 1

Step-by-step explanation:

4x+3y = 2100 -------(1)

5x+2y = 1750 -------(2)

(1) × 2 =>> 8x+6y = 4200 -----(3)

(2) × 3 =>> 15x+6y = 5250 -----(4)

(4) - (3) =>> 7x = 1050

=>> x = 150

Substituting x=150 in (1) = 4(150)+3y = 2100

= 600+3y = 2100

= 3y = 2100-600

= 3y = 1500

= y = 500

Therefore values,

x = 150 , y = 500

Answer 2

Answer:

4X+3Y=2100

5X+2Y=1750
