2s + s + 12 = 132 3s + 12 = 132 3s = 132 - 12 3s = 120 s = 40
2h2s + so2 - 2h20 + 3s
135=3s +15 120=3s 40=s
No.
12r - 15s - r + 3s = 11r -12s
math
2t-4s
3s + 4t + 2s + 5s + 6tGroup all of the like 's' terms & 't' terms together:(3s+2s+5s) + (4t + 6t)10s + 10t or 10(s+t)
You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
-7 = 3s - 1 +1 +1 (add 1 to both sides to get the variable alone) ___ ____ -6 = 3s __ ___ (-6 and 3s both divided by 3) 3 3 -2 = s
Simplified its 12r+3s
2s + s + 12 =132 ie 3s = 132 -12 3s = 120 s = 40
