What is the solution to this 2x+1+x=3(x-2)+7

infinite solutions

x is all real numbers

Step-by-step explanation:

2x+1+x=3(x-2)+7

Distribute

2x+1 +x = 3x -6+7

Combine like terms

3x+1 = 3x+1

Subtract 3x from each side

3x-3x+1 = 3x-3x+1

1=1

This is always true, so it doesn't matter what value we put in for x

X is all real numbers

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
