Answer:
5x + 2 - 2(x - 1) = 3x + 4
⇔ 5x + 2 - 2x + 2 = 3x + 4
⇔ 3x + 4 = 3x + 4
⇔ 4 = 4
⇒ infinite solutions
Step-by-step explanation:
The difference between 342 and 324 is different because the digits 2 and 4 are flipped.
342 and 324 are alike because they have the same amount of digits. hope that helped.
So,
First you have to distribute the numbers outside of the parentheses (you multiply them with the numbers inside of the parentheses
-18+(-9a) + 8a +36=11
Then collect like terms
18-1a =11
-18 -18
---------------------
-1a=-7
Divide both sides by -1
a=7
