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

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
