Question

Use the substitution method to solve the system of

equations.
5x + 2y = 1
y = -x + 2
A. (-3Ė5)
B. (-3Ė8)
C. (-1Ė3)
OD. (-2Ė4)

Answer 1

C (-1,3)

Explanation:

a) 5x + 2y = 1

b) y = - x + 2

a) 5x + 2(-x + 2) = 1

5x - 2x + 4 = 1

3x = -4+1

x = -3/3

x = -1

b) y = - - 1 + 2

y = 1 + 2

y = 3
