Step-by-step explanation:
3x-21+20=12+2x-6
3x-1= 6+2x
3x-2x=6+1
x=7
Answer:
m=1
Step-by-step explanation:
step 1: 8(m + 2) = 3(12 - 4m) remove the parentheses
step 2: 8 m + 2 = 3 12 - 4m move the terms
step 3: 8m+ 12m= 36 - 16 collect like terms and calulate
step 4: 20m=20 divide both sides
solution: m=1
The answer is 17 because a right angle is 90 and you subtract 73 from it and get 17
