first get the left hand side to only contain x's
this requires you to get rid of the 9 on the left hand side
so minus 9 on both sides of the equal sign
so 8x + 5x + 9 = 61 becomes 8x + 5x +9 -9 = 61 -9 which is 8x + 5x = 52
now add the x's
so 13x = 52
then divide both sides by 13 to find the value of x
x = 4
8x + 5x + 9 = 61 Collect 'like' terms. 13x + 9 = 61 Subtract '9' from both sides 13x = 52 Divide both sides by '13' x = 52/13 x = 4
B=61

If: 7+3b = 61 Then: b = 18
The Identity Property of Addition
8x + 5x + 9 = 61 Collect 'like' terms. 13x + 9 = 61 Subtract '9' from both sides 13x = 52 Divide both sides by '13' x = 52/13 x = 4
B=61
61
x/2 - 5x/(61/9) = x/2 - 5x(9/61) = x/2 - 45x/61 the least common denominator is 122 = [(x)(61)]/122 - [(45x)(2)]/122] = (61x - 45x)/122 = 16x/122 = (16x ÷ 2)/(122 ÷ 2) = 8x/61

x= 119
You can't do that because 12 plus 60 plus 61 equals 173 unless yo take out the twelve but if you can only use the given variables then you cant do that

If the question means solve 1+2+...+60 then 1+2+...+n = n(n+1)/2 for any integer n>0 So for n= 60 the sum is 60*61/2 = 30*61 = 1830
9x - 20 = 61 Add 20 to both sides: 9x = 81 Divide both sides by 9: x = 9
