Answer:
x = - 3, y = - 1
Step-by-step explanation:
y = 7x + 20 -----> equation 1
4x - y = - 11
4x - ( 7x + 20 ) = - 11
4x - 7x - 20 = - 11
- 3x = - 11 + 20
- 3x = 9
x = 9 / - 3
x = - 3
Substitute x = - 3 in equation 1,
y = 7 ( - 3 ) + 20
= - 21 + 20
y = - 1
Hence,
x = - 3
y = - 1
12...? I think?
Since she has 9 left and it only says that she gave 3 away..
Answer:
r = 94
Step-by-step explanation:
Solve the equation by isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 26 to both sides:
r - 26 (+26) = 68 (+26)
r = 68 + 26
Add:
r = 94
r = 94 is your answer.
