Answer:
26 1/4
Step-by-step explanation:
start by converting 2x to 6/3 x so your x coefficients have common denominators and can be added
2/3 + 6/3 = 8/3
8/3 x = 70
multiply both sides by 3/8 to move the 8/3 to the other side.
x = 210/8 or 26 1/4
Answer-
x=104/3
Step-by-step explanation:
1. (2x)+(2/3+20)=90 (combine like terms)
2. 2x+62/3=90
3. subtract 63/3 from both sides 2x+62/3-62/3=90-62/3
The answer you get is 2x=208/3 but you need to divide it by 2 so
2x/2= x and 208/2=104/3
