What is the value of s? 0.7(3s+4)−1.1s=7.9

Before isolating s we need to simplify the equation using order of operations.
.7(3s+4)-1.1s = 7.9 > First distribute the .7
2.1s + 2.8 - 1.1s = 7.9 > Now combine like terms
s + 2.8 = 7.9 > Now to isolate s by subtracting 2.8 from both sides!

s = 7.9 - 2.8
s = 5.1
