Answer:
a=1, b=1
Step-by-step explanation:
Given the equation: [tex]a(3 - x) = - 2x + b[/tex]
If the solution of the equation [tex]x=-2[/tex]
Then to find the values of a and b, we substitute [tex]x=-2[/tex] into the equation.
[tex]a(3 - x) = - 2x + b\\a(3 - (-2)) = - 2(-2) + b\\a(3+2)=4+b\\5a=4+b\\5a-b=4\\$If we make the substitution a=1, b=1 into the above equation\\5(1)-1=4 is true.\\Therefore: a=1, b=1[/tex]
