50 points. The expressions a(8x +7) and 4x +3.5 are equivalent What is the value of a? 50 points if right i will mark brainiest answer asap to for test help! Show your work please.

a(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4  so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2

 A(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4  so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2
