Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a> 1

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
