Question

Please help. Solve 5x + 7 > 17.

Answer 1

Answer:

$\large\boxed{\{x\ |\ x>2\}}$

Step-by-step explanation:

$5x+7>17\qquad\text{subtract 7 from both sides}\\\\5x+7-7>17-7\\\\5x>10\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}>\dfrac{10}{5}\\\\x>2$

Answer 2

This question is just like algebra. The gt sign is similar to an equal sign.
You want to isolate the variable (x) on one side.
And the numbers on the other side of the sign.
Then continue with algebra-
Make sure you don’t touch the sign or switch it.
You ONLY switch the sign if your dividing by a negative number.
Hope this helped.
