Maeve Graves · Answer 1

4a+4=20+b

If a = 5 and b = 4

then the equation would be:

20+4=20+4

24 = 24

That works out to be true

A = 5 B = 4 X = 4

Keyla · Answer 2

Ax+4=5x+b ... 1

Substituting x=0 into 1,

0+4=0+b

b=4

Substituting b=4 into 1,

ax+4=5x+4

ax+4-5x-4=0

ax-5x=0

ax=5x

a=5x/x

a=5

Therefore, a=5 and b=4

Enter values of a and b for which x=4 is a solution of the equation shown.ax+4=5x+b

Enter values of a and b for which x=4 is a solution of the equation shown.
