Question

Solve the following equation using the substitute method
5x+y=9
2x-3y=-10

Answer 1

Answer:

(x,y)=(1,4)

Step-by-step explanation:

y=9-5x

substuting in equation

2x-3y=-10

2x-3×(9-5x)=-10

2x-27+15x=-10

17x=-10+27

x=17/17

x=1

substuting x=1 in equation

5x+y=9

5+y=9y

=9-5=4

Answer 2

Answer:

x = 1

Step-by-step explanation:

(5x+y=9)*3 = 15x+3y=27__ (a)

2x-3y=-10___(b)

add equation no (a) and (b)

15x+3y=27

2x-3y=-10

__________

17x = 17

x = 17/17

x= 1 Ans
