Decreasing half of a number by 19.7 results in –4.1. What is the number? Use the given equation to find the number.

One-halfx – 19.7 = –4.1

Asap (explain how you got it as well for brainliest)i tried 1: 2 and 2: 3 and they were wrong.picture of figure: in the figure below, the segment is parallel to one side of the triangle. the ratio of 12 to y is1: 21: 31: 42: 3

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
