Answer 8

Solve the system, using substitution.
3a - b = 11 and 2a + 3b = 0
A. (3, 2)
B. (3, -2)
C. (-3, 2)
D. (-3, -2)
E. no solution

Answer 9

Perimeter is P length = l and width = w


P = 2l + 2w

so

50 = 2l + 2w

then you know after dividing by 2

25 = l + w this is 1 equation

and you know length is 4 longer than width

l - w = 4 this is the other equation

so there are your 2 equations.

now you can solve the equations

Answer 10

it got B. (3, -2)
