I don’t understand the question so I answer in two ways
Answer:
Okay! It should be the 3 one.
-2(3)+30=24
Step-by-step explanation:
1.8- 3.7x = 4.2x + 0.3
Move 4.2x to the other side
Sign changes from +4.2x to -4.2x
1.8-3.7x-4.2x= 4.2x-4.2x+0.3
1.8-3.7x-4.2x= 0.3
1.8-7.9x= 0.3
Move 1.8 to the other side
Sign changes from +1.8 to -1.8
1.8-1.8-7.9x= 0.3-1.8
-7.9x= 0.3-1.8
-7.9x= -1.5
divide both sides by -7.9
-7.9/-7.9x= -1.5/-7.9
x= 0.18987341
Answer: x= 0.18987341
Answer:
1/2 X + X -15 + 1/2 X + 100 + X -25 = 540
1/2x + x + 1/2x + x -15 + 100 -25 = 540
3 x + 60 = 540
3x + 60 - 60 = 540 - 60
3/3x = 480/3
x = 160
Step-by-step explanation:
1/2 X + X -15 + 1/2 X + 100 + X -25 = 540
1/2x + x + 1/2x + x -15 + 100 -25 = 540
3 x + 60 = 540
3x + 60 - 60 = 540 - 60
3/3x = 480/3
x = 160
