Subtract 13 from both sides:
[tex] -7-13 \geq -5x [/tex]
[tex] -20 \geq -5x [/tex]
Divide both sides by -5. Since this is a negative number, you have to invert the inequality sign:
[tex] 4 \leq x [/tex]
Which means
[tex] x \geq 4 [/tex]
Hi Valblessed,
Solve:
−7 ≥ 13 − 5x
−7 ≥ −5x + 13
−5x + 13 ≤ − 7
−5x + 13 − 13 ≤ − 7 − 13
−5x ≤ − 20
−5x/−5 ≤ −20/−5
x ≥ 4
Answer:
x ≥ 4
