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!
