Question

4-(1/2x +3/4)=-1,5

Answer 1

\(4-\left(\frac{1}{2}x+\frac{3}{4}\right)=-1,5\)

=> \(\frac{1}{2}x+\frac{3}{4}=4-\left(-1,5\right)\)

=> \(\frac{1}{2}x+\frac{3}{4}=5,5\)

=> \(\frac{1}{2}x=5,5-\frac{3}{4}=\frac{19}{4}\)

=>\(x=\frac{19}{4}:\frac{1}{2}=\frac{19}{2}\)

Answer 2

4-(1/2x+3/4)=-1,5

=>1/2x+3/4=4-(-1,5)

=>1/2x+3/4=5,5

=>1/2x=5,5-3/4

=>1/2x=4,75

=>x=4,75:1/2

=>x=9,5
