Question

Examine the system of equations,

y = 5x + 6,
y = x + 10
Use substitution to solve the system of equations
What is the value of y?
0-11
O-1
0 1
011

Answer 1

Answer:D

Explanation:

11

Answer 2

y= 11

Explanation:

First label the 2 equations.

y= 5x +6 -----(1)

y= x +10 -----(2)

susbt. (1) into (2):

5x +6= x+10

5x -x= 10 -6 (bring x terms to 1 side, constant to the other)

4x= 4 (simplify)

x= 4 ÷4

x= 1

susbt. x=1 into (2):

y= 1 +10

y= 11 (simplify)

Thus, the value of y is 11.
