<span>Pick two pairs: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Eliminate the same variable from each system: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Solve the system of the two new equations: -5y - 5z = - 10. 5y - 7z = 34. ... Substitute into one of the original equations: - x + 2y - 5z = 17. ... <span>Check: Does 2(1) + 4 + 3(- 2) = 0 ? Yes.</span></span>

Please help with this I’m garbage at math:/
Ronch [10]

Answer:

Thale's theorem stated that if a line parallel to the base of the triangle intersects it, the ratio of sides of the respective sides is equal

In this diagram, since the 2 horizontal lines are parallel

the ratio of the 2 sides on the left and the 2 sides on the right will be equal

Hence,

x/15 = 2/10

x = 30/10

x = 3
