What is the solution to the following system of equations? 27-9x=-7y 45+7y=9x

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
