Answer:

there are only one solutions

Explanation:

why there is only one solutions because

4(x - 5) = 3x + 7

4x - 20 = 3x + 7

+ 20 = + 20

4x = 3x + 27

-3x -3x

1x = 27

x = 27

so therefore A.1 is the answer

Answer:

1 solution

Explanation:

4(x-5)=3x+7

4x - 20 = 3x + 7

y = 4x - 20 and y = 3x + 7 are straight lines with different slopes, so they must intersect at exactly 1 point.

1 solution
