1) g+4-3g=1+g subtracting g from both sides 4-3g=1 subtracting 4 from both sides -3g=-3 g=1 2) -6a+3=-3(2a-1) extending the right side -6a+3=-6a+3 adding 6a to both sides 3=3 which is an identity 3) 0.5b+4=2(b+2) extending the right side 0.5b+4=2b+4 subtracting 0.5 b from both sides 4=1.5b+4 subtracting 4 from both sides 0=1.5b b=0 4) 8-(3+b)=b-9 subtracting 8 from both sides -(3+b)=b-17 extending the left side -3-b=b-17 adding b to both sides -3=2b-17 adding 17 to both sides 14=2b b=7
