Question

Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
y = 4x - 2
y = x + 13
A. (1, 13)
B. (0, -2)
C. (5, 18)
D. (4,-2)

Answer 1

Answer:

c

Step-by-step explanation:

just plug each coordinates

5=x

18=y

if its tru for both then thats the answer

Answer 2

Answer:

5,8

Step-by-step explanation:

y=4x-2-----(i)

y=x+13----(ii)

Equating equation i and ii we get,

$4x - 2 = x + 13$

$4x - x = 13 + 2$

$3x = 15$

$x = 3$

$substitutin \: the \: value \: of \: x \: in \: equation \: (i)$

$y = 4x - 2$

$y = 4 \times 5 - 2$

$y = 20 - 2$

$y = 18$

Marks this as a brainest answer ok.
