Question

Solve the system of linear equations below.

y = -2x + 19
y = x + 7

Answer 1

Substitute the 2nd equation into the first equation
x+7=-2x+19

Answer 2

i got x = -2x + 12

Answer 3

x+7=-2x+19
3x = 12
x=4
To get y, substitute 4 into the eq above to get y
4+7=y
11=y

check to be sure both eq work
-2(4) +19 =y
-8+19 =11

solution is always an ordered pair (4,11) Knowing that will make your teacher happy

Answer 4

thank you
