a [tex]\leq[/tex] 7
because 4a + 7 - 7 [tex]\leq[/tex] 35 - 7
equals 4a [tex]\leq[/tex] 28
and 4a/4 [tex]\leq[/tex] 28/4
equals a [tex]\leq[/tex] 7
Answer:
Step-by-step explanation:
[tex]4a+7\leq35\qquad\text{subtract 7 from both sides}\\\\4a+7-7\leq35-7\\\\4a\leq28\qquad\text{divide both sides by 4}\\\\\dfrac{4a}{4}\leq\dfrac{28}{4}\\\\a\leq7[/tex]
