0.7 (3s + 4)-1.1s = 7.9
vichka [17]

Answer:

s = 5.1

Step-by-step explanation:

0.7 (3s + 4)-1.1s = 7.9\\

Multiply both sides of the equation by 10

0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\

Expand

\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28

Subtract 28 from both sides

10s+28-28=79-28

Simplify

10s=51

Divide both sides of the equation by 10

\frac{10s}{10}=\frac{51}{10}

Simplify

s=\frac{51}{10}\\\\Decimal = 5.1
