Question

Which value of X Satisfy 2(x +5.3) =4.2

Answer 1

This question simply means we should find the value of x,

`2\mleft(x+5.3\mright)=4.2`

First we expand by using 2 to multiply the items in the bracket, we have

`\begin{gathered} 2* x+2*5.3=4.2 \\ 2x+10.6=4.2 \\ 2x=4.2-10.6 \\ 2x=-6.4 \\ \text{dividing both sides by 2, we have } \\ (2x)/(2)=(-6.4)/(2) \\ x=-3.2 \end{gathered}`

Hence the answer is -3.2
