Sagot :
Answer:
40.25
Explanation:
2(2x - 5 - 4) = 160 -17
first we do the first half on the left
2 × 2x = 4x
2 × -5 = -10
2 × -4 = -8
then the right
160 - 17 = 143
next is
4x - 10 - 8 = 143
we add 10 and 8, which equals - 18
4x - 18 = 143
after that we transfer the -18 to the other side to 143
4x - 18 = 143
+ 18 = +18
4x = 161
then we divide 4 on both sides
4x/4 = 161/4
x = 40.25 or 40.3 if you have to round up
2(2x - 5- 4) = 160 - 17
4x - 10 - 8 = 143
4x -18 = 143
4x = 143 +18
4x = 161
4x/4 = 161/4
X = 40,25
4x - 10 - 8 = 143
4x -18 = 143
4x = 143 +18
4x = 161
4x/4 = 161/4
X = 40,25
