you use P.E.M.D.A.S. for all the equations.

so you do thr multiplication and then the addition

1. 2(1.8)+3.5= 3.6+3.5= 7.1

2. 2(4)+3.5= 8+3.5=11.5

3.2(6.9)+3.5= 13.8+3.5= 24.2

If y + 2q = 15, q + 2p = 5 and p + 2y = 7, then ﬁnd<br> the value of p + q + y.

notsponge [240]

$y+2q=15\\
y=15-2q\\\\
p+2y=7\\
p+2(15-2q)=7\\
p+30-4q=7\\
-3q+30=7\ \ \ |Subtract\ 30 \\
-3q=-23\ \ \ |Divide\ by\ -3\\
q=\frac{23}{3}\\\\
y=15-2q=15-2(\frac{23}{3})=15-\frac{29}{3}=15-7=8\\\\
p=7-2y\\
p=7-2*8\\
p=7-16=-9\\\\
\textbf{p+q+y=}-9+\frac{23}{3}+8=-1+7\frac{2}{3}=\boxed{6\frac{2}{3}}
