Answer:

x is 35

Step-by-step explanation:

First do 180 -40 and get 140. Then add 3x plus x to get 4x because they are the same value/ Do 140/ 4x and get 35. X equals 35.

Answer:

35, 135

Step-by-step explanation:

You first add the like terms. 3x + x = 4x. Next you form an inequality.

40 - 4x = 180.

x = 35

Since x equals 35 you do 3 * 35. 3(35), which is 105.

35 + 40 + 105 = 180!
