Answer:
x ≥ -4
Step-by-step explanation:
-3x + 2 ≤ 14
Subtract 2 from each side
-3x+2-2 ≤ 14-2
-3x ≤ 12
Divide each side by -3 . Remember that dividing by a negative flips the inequality.
-3x/-3 ≥12/-3
x ≥ -4
Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
