Answer:
[tex]b=2a +\frac{7}{2}[/tex]
Step-by-step explanation:
[tex]4a=2b-7[/tex] solve for b
To solve for b, we need to get b alone
We need to remove -7 to isolate 2b
[tex]4a+7=2b-7+7[/tex]
[tex]4a+7= 2b[/tex]
To get 'b' alone we divide both sides by 2
[tex]\frac{4a}{2} +\frac{7}{2} =b[/tex]
[tex]2a +\frac{7}{2} =b[/tex]
[tex]b=2a +\frac{7}{2}[/tex]
