51) 5x-1=0 and x+6=0
5x=1, x=1/5 and x=-6
2 solutions x=1/5 and x=-6

52)x(2x+3)=0
2x=0 and 2x+3 =0
x=0 and x=-3/2=-1.5

53) x(5x-1)=0
x=0 and 5x-1=0
x=0 and x=1/5

54) z(4z+7) =0
z=0 and 4z+7=0
z=0 and z= - 7/4 = -1.75
z=0 and z=-1.75

Answer: $(-1.412,-2.124),(3.29,7.28)$

Step-by-step explanation:

Given

The given equation is $2^x-2.5=2x+0.7$

There are two functions i.e. $y=2^x-2.5\ \text{and}\ y=2x+0.7$

Their intersection gives the solution of the above function

From the graph, we can see that both the graph intersects at two different points i.e. at

$(-1.412,-2.124)\ \text{and}\ (3.29,7.28)$
