The solution of the following equation is obtained by using the function image and checked by written calculation （1）5x-1=2x+5；(2)-1/2x+4=3/2x+2

This one has to draw. This one is a little inconvenient
But I'll tell you the way. I hope it will help you
(!) the two ends of the equal sign are y = 5x-1
Y = 2x + 5 take the dotted line as accurately as possible, there will be an intersection in the graph, and the abscissa of the intersection is the x value
Then we take the value of X into y = 5x-1
Y = 2x + 5 to see if the two Y values are equal. This is the test
The second is the same. Y =) - 1 / 2x + 4
y=3/2x+2
By drawing and doing, we will have a better understanding of the meaning of the intersection of function images
