Question

y=4x-3
10x-y=27

solve using substitution method.

Answer 1

10x-(4x-3)=27
6x+3=27
6x=24
X=4

Answer 2

Answer:

x=4 , y= 13

Step-by-step explanation:

y = 4x – 3

10x – y = 27 ——— eq.2

On putting y= 4x – 3 in eq.2 , we get

10x – ( 4x – 3 ) = 27

10x – 4x + 3 =27

6x = 27 – 3

6x = 24

x = 24/6

x= 4

On putting x=4 in eq.1, we get

y = 4×4 – 3

y = 16 – 3

y = 13

Hope it helps you dude

Have a great day
