Solve the system of linear equations by substitution
x-y=4
2x-3y=3

x=9. y = 5. (9,5)

Step-by-step explanation:

x-y=4. Solve for x or y

+y. +y

x= 4+y

2x-3y=3. Substitute

2(4+y) - 3y=3

8+2y -3y =3

8-y = 3

-8. -8

-y = -5

-1(-y = -5)

y = 5

x - y = 4

x - 5 = 4

+ 5. +5

x=9

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
