Answer:

x = 3, and y = 2

Step-by-step explanation:

2x + 3y = 12 -------- (1)

y = x - 1 ---------------(2)

Substitute value of Y in (2) in (1)

2x + 3(x-1) = 12

2x + 3x - 3 = 12

5x - 3 = 12

5x = 12 + 3

5x = 15

x = 15/5

x = 3

Put the value of x in equation 2

y = x-1

y = 3 - 1

y = 2

Therefore, x = 3, and y = 2

Factor each expression. (9) 5a - 25 (10) 28 - 7x (11) 12z + 28 - 7z - 3

Nimfa-mama [501]

Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25 ( GCF is 5 so take out 5 and divide every term by 5)

5(a-5)

(10) 28 - 7x ( GCF is 7 so take out 7 and divide every term by 7)

7(4-x)

(11) 12z + 28 - 7z - 3= (combine terms) =

5x+25( GCF is 5 so take out 5 and divide every term by 5)

5(x+5)
