Answer:
[tex]-9.2(4 - x) = -18.4[/tex]
[tex]-36.8 + 9.2x =-18.4[/tex]
Explanation:
Given
[tex]-9.2(4 - x)[/tex]
[tex]-36.8 + 9.2x[/tex]
Required
Evaluate when [tex]x =2[/tex]
[tex]-9.2(4 - x)[/tex]
Substitute 2 for x
[tex]-9.2(4 - x) = -9.2(4 - 2)[/tex]
Evaluate the expression in bracket
[tex]-9.2(4 - x) = -9.2(2)[/tex]
Remove bracket
[tex]-9.2(4 - x) = -9.2*2[/tex]
[tex]-9.2(4 - x) = -18.4[/tex]
[tex]-36.8 + 9.2x[/tex]
Substitute 2 for x
[tex]-36.8 + 9.2x = -36.8 + 9.2 * 2[/tex]
[tex]-36.8 + 9.2x = -36.8 + 18.4[/tex]
[tex]-36.8 + 9.2x =-18.4[/tex]
