Question

What is the value of x in the equation 2(2x − 5 − 4) = 160 − 17? 40. 25 62. 25 80. 25 143. 0.

Answer 1

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

Answer 2

40.25

Step-by-step 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
