Answer:
Step-by-step explanation:
4x - 3/2 - 5 - 2x/3 - 3x - 4/3 = 5
Give all terms least common denominator of 6:
4x(6/6) - 3/2(3/3) - 5(6/6) - 2x/3(2/2) - 3x( 6/6)- 4/3(2/2) = 5(6/6)
24x/6 - 9/6 - 30/6 - 4x/6 - 18x/6 - 8/6 = 30/6
Combine x terms and numerical terms:
2x/6 - 47/6 = 30/6
2x/6 = 77/6 (Add 47/6)
2x = 77 (Multiply both sides by 6)
x = 77/2 = 38.5

in that order buddy make it exactly like this :)
Answer:
x = 31
Step-by-step explanation:
AC=BD
3x+7 = 131-x
Subtract 7 from both sides
3x = 124-x
Add x to 3x
4x = 124
Divide by 4
x = 31
Check:
3(31)+7 = 131 - 31
Mulitply 3 times 31 / subtract 131 and 31
93+7 = 100
Add 93 to 7
100 = 100
