Thesolutionfor the given system of linear equations is (-1, 4).What is a linear system of equations?A system oflinear equationsconsists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.The given system ofequationsare 3x-3y=-21 ----(i) and 3x+3y=15 ----(ii).Add equation (i) and (ii), we get3x-3y+(3x+3y)=-21+156x=-6x=-1Substitute x=-1 in equation (i), we get3(-3)-3y=-21-9-3y=-21-3y=-12y=4Therefore, thesolutionfor the given system of linear equations is (-1, 4).To learn more about thelinear system of an equationsvisit:brainly.com/question/27664510.#SPJ1...
