Solve the system of linear equations:
y = x - 4
4x + y = 26
HINT: Use substitution or combine to solve.
x = 6
y = 2

Solve the inequality:
15 + x >= 7
x >= -8 OR -8 <= x
400
Solve the system of linear equations:
2x + 3y = 31
y = x + 7
HINT: Use substitution or combine to solve.
x = 2
y = 9

4/3 t + 5 > 1/3 t
t > -5 OR -5 < t
500
Solve the system of linear equations:
5p + 3q = 4
7p + 2q = 21
HINT: Use substitution or combine to solve.
p = 5
q = -7
